Osprey Aura AG LT is best for:

• Backpackers of all skill levels
• Long treks requiring heavier loads 
• Shoppers looking for a one-and-done kit 

Osprey Aura AG LT might not be a fit for:

• Organizational fanatics — these features are pretty minimal 
• Ultralight enthusiasts  

I’ve given the Osprey Aura AG LT 65 a rating of 4.7 out of 5 stars. It”s a lighter pack than the previous model with minimalist organization features. Yet, its main compartment and external pockets offer an impressive volume of 63L. The pack can also carry up to 40 lbs (18.1 kg), ideal for multi-day trips and even long thru-hikes. 

Ultralight enthusiasts will appreciate its removable base straps and detachable lid. Meanwhile, those looking for a complete one-and-done kit will like that the pack comes with an integrated rain cover. In addition, the Osprey Aura AG LT is made with durable, eco-friendly materials and has a stylish aesthetic. In my opinion, its value is fairly on point with a $290 price tag. 

However, no product is perfect and my greatest concern with the pack is an important one: comfort. Within 6 miles of hiking, Skycie had a significant welt on her left hip. Her load may have been a touch too heavy, or maybe it was how she had the bag packed. Maybe there was an issue in fitting the pack. Regardless, this was cause for concern.

To give it another chance, I tested it out personally and was very careful when fitting and packing the bag. I found the Aura to be comfortable, but undoubtedly, its contoured hip belt is more rigid than other packs. Load transfer is crucial, but arguably, this belt may hug a bit too tight. 

My other qualms with the pack are more minor. For one, a thinner (but still durable) fabric may have made this pack even lighter. I wish its internal hydration sleeve were more versatile, rather than specific to the Osprey brand. Its top lid could also be easier to remove, and the ability to tuck in the waist belt straps would have created a more seamless look. 

But remember, it’s my job to be critical when writing these reviews. Overall, I think the Osprey Aura AG LT is a stellar choice, especially for long treks that require heavier loads.

👉 Pro Tip: If you’re worried about comfort, visit REI for a professional fitting. Also, be judicious about what you store in the hip belt pockets, and don’t carry more weight than your body can manage. Of course, testing the pack on shorter trails before a big expedition is a great idea, too.

Osprey Aura AG LT Features Review

That’s the quick summary of my Osprey Aura AG LT review. Now, let’s go over each of its features in greater detail. You’ll know exactly what to expect from this pack by the end of this section! 

Below, I cover each of the following Osprey Aura AG LT details. If you’d like, use the jump links here to skip ahead to each topic: 

Size 

⭐ STAR RATING: 5 / 5 stars

The Osprey Aura AG LT 65 is a spacious pack. It can easily hold enough gear for multi-day hiking trips, including long thru-hikes. Its extra small/small size has a volume of 63L. 

Using plastic golf balls, I completed a test to demonstrate each compartment’s volume. This is similar to ASTM International’s standard test for backpack capacity. Estimating that there are 12 golf balls per liter, here’s a breakdown of my findings:

• Top lid – 205 golf balls / 17.1L 
• Front pocket (with the main compartment empty) – 112 golf balls / 9.3L 
• Side pockets (2x) – 95 golf balls / 7.9L
• Hip belt pockets (2x) – 15 golf balls / 1.25L
• Base pocket – 46 golf balls / 3.8L 

Given its 63L total, this infers that the main compartment is roughly 14.5L. This may seem small, but consider my note above — these pockets were measured with the main compartment empty. If the main compartment were full, it would take significant volume away from the front, base, and side pockets. 

It isn’t a perfect system, but this test helped to indicate each section’s maximum capacity. Doing so made me realize the spaciousness of the top lid, especially. It’s one of the largest of any other pack I tested. For further comparative data, review the chart on our “Best Backpacking Pack” round-up.

Weight

⭐ STAR RATING: 5 / 5 stars

As the name suggests, weight is the greatest difference between the Osprey Aura AG 65 and its new LT (light) model. The original model weighs 4.467 lbs (2.026 kg), while the Osprey Aura AG LT 65 clocks in at just 3.837 lbs (1.740 kg). 

When it comes to backpacking, even a 0.63-lb (0.286-kg) difference is impactful. Its simplified organization is what allowed for this 14.1% reduction in weight. 

Yet, Osprey kept the pack’s most important organization features and maintained its load capacity. Impressively, the Osprey Aura AG LT 65 can carry up to 40 lbs (18.1 kg).

👉 Pro Tip: Just because a pack can carry heavier loads doesn’t mean you should. Experts suggest that your pack weighs no more than ~20% of your body weight. 

Height Adjustable

⭐ STAR RATING: 5 / 5 stars

The Osprey Aura AG LT’s height adjustable feature is extremely user-friendly. To fit the pack to your torso length, simply move the ladder adjustment system up or down. Its injection molds latch securely and accommodate a 4-in (10.2-cm) range. For example, the extra small/small size caters to a torso length of 13-17 in (33-43.2 cm).

Comfort 

⭐ STAR RATING: 4 / 5 stars

Compared to the Osprey Aura AG 65, the brand claims that the light version doesn’t “compromise on comfort.” Skycie put this to the test, and unfortunately, her experience differed.

By the end of our 6-mile (9.7-km) hike, she had a pretty significant welt on her left hip. Could this have been due to her carrying more than 20% of her body weight? Perhaps. Could this pocket have been overfilled? Maybe. 

But I had a feeling it was due to the pack’s extremely rigid hip belt. It’s padded and contoured, like many of the backpacking packs I tested for this project. However, it’s very thick with almost zero give.

To give the pack a second chance, I took it out on another 6-mile (9.7-km) hike. My pack’s weight totaled 18.4 lbs (8.3 kg), which is less than 20% of my body weight. To test all variables, I also put smaller items in the hip belt pockets and was very careful in fitting the pack. 

In my experience, I found the Osprey Aura AG LT 65 to be reasonably comfortable. Its anti-gravity suspension system performed well and the back panel felt breathable. Its shoulder straps didn’t bite, nor did the hip belt — except for in one instance.

At one point, the zipper of my jacket pocket pressed against my hip bone. I noticed discomfort due to the hip belt within just a few minutes. It wasn’t a big deal, as shifting my jacket fixed the issue. But still, something worth noting. 

If the waist belt compresses any pockets, make sure that they’re empty to avoid similar issues. Overall, the Aura AG LT 65 should treat you well if you take these outlined precautions.

Internal Organization

⭐ STAR RATING: 4.5 / 5 stars

The Osprey Aura AG LT has limited internal organization features, as you’ll find on most backpacking packs. And like similar models, it features top access. 

But what I especially love about this pack is side access to the main compartment. If looking at the front face, you’ll find a vertical zipper on the left side. I wouldn’t recommend loading your pack this way, but it’s a handy feature that makes grabbing gear or an extra layer easy. 

In addition, the Osprey Aura AG LT has an internal hydration reservoir sleeve. It will fit a variety of reservoir sizes. But the piece that holds the pouch in place is specifically designed for the Osprey brand’s reservoirs. I wish this were more versatile, like the side-release buckle seen on the Osprey EJA.

The port on the Osprey Aura AG LT, though, is very standard. Draw the hose through the opening found in the center of the upper back panel. You can then secure the hose through the elastic bands on either the left or right shoulder strap.  

External Organization

⭐ STAR RATING: 4.5 / 5 stars

Osprey streamlined its organization features on the light version of this pack. What it kept, though, is highly useful, especially for bulky gear.

At the base of the pack lie two removable compression straps. These are great for your sleeping pad, backpacking tent, or bear canister. You can also treat them like a sleeping bag compartment. 

The front face of the pack features a large shove-it pocket. There’s elastic at its mouth, as well as a side-release buckle to secure your items. The pocket is also fabric reinforced, further protecting your gear from the elements.  

You’ll find two compression straps on either side of the pack, which complement the two ice axe loops. Of course, these straps can be used for other gear, too, like trekking poles or a sleeping pad. 

The pack also has two deep water bottle pockets on either side. These fabric-reinforced pockets feature dual access. As Skycie demonstrates above, you’ll need to loosen the compression strap to get your bottle to fit through the upper opening. Do so if storing a tall 48-oz Nalgene bottle here, or maybe other types of gear. 

But for her standard 32-oz Nalgene, Skycie solely relied on these pockets’ side access. Conveniently, you can remove and replace your bottle from here without taking off your backpack.

The Osprey Aura AG LT also has dual hip belt pockets. These hip belt pockets are great for storing smaller items you’ll want easy access to, like sunscreen, lip balm, and snacks. Though, as a comfort precaution, avoid storing anything bulky here.  

Lastly, the pack has a spacious pocket on its lid, which you can access from its external zipper. The top lid also features four web lash points for storing additional gear. 

If you find that you don’t need this extra storage, you can remove the brain and cut down on weight. Do so by unclipping the two side release buckles on the front, and undoing the straps on the backside. Then, clip down the integrated flap jacket to protect the main compartment. 

👉 FYI: I wish that Osprey made removing the lid a bit easier, with side release buckles on all attachment points. This is what you’ll find on the REI Co-Op Flash 55 backpack. Keep this pack in mind if you like customizable features!

Rain Cover

⭐ STAR RATING: 5 / 5 stars

The Osprey Aura AG LT is water-resistant but also comes with an integrated rain cover. This is convenient for times of heavy rain and snowfall. It has a dedicated compartment at the base of the pack and can be removed to cut down on weight. Though, I’d only recommend doing so if you’re confident you won’t encounter precipitation on the trail. 

Materials

⭐ STAR RATING: 5 / 5 stars

The primary shell of this pack is a recycled 210D nylon honeycomb contrast. It also has a DWR (durable water repellent) coating that is PFAS-free. This means it does not leach harmful per-and poly-fluoroalkyl substances into the environment.

Its accent fabric is recycled 210D high-tenacity nylon, also with a PFAS-free DWR. Its base fabric is similar: a recycled 500D high-tenacity nylon with a PFAS-free DWR. 

“D” refers to the denier or the thickness of the fabric. Higher numbers indicate greater thickness. Interestingly, the light version of the pack uses the same fabric thickness as the original Osprey Aura AG 65. Arguably, this makes the pack equally as durable — but could Osprey have saved even more weight by choosing a thinner material? I think so. 

For example, the extra small/small Osprey Eja 58 may be slightly smaller (55L) than the Osprey Aura AG LT 65 (63L). But the Eja’s 100D main fabric largely accounts for its low weight of just 2.717 lbs (1.232 kg).  

The Aura AG LT with 210D fabric weighs 3.837 lbs (1.740 kg) — which is 41% more than the comparable Eja model.  Point being, if you’re looking for an ultralight pack, you may find other products’ fabric choices more compelling.

But that aside, I love that Osprey uses eco-friendly materials for the Aura AG LT. I’m also a fan of its unique honeycomb ripstop fabric. Due to this unique threading, if a tear occurs, the fabric won’t continue unraveling. High-tenacity nylon also protects against abrasion and makes the pack extra durable.  

Hardware 

⭐ STAR RATING: 5 / 5 stars

All of the plastic hardware on the Osprey Aura AG LT is of high quality. This includes the side release buckles, as well as the ladder locks and triglides on the straps. The same can be said of the drawstring cord lock.

As for metal hardware, the zippers on the Osprey Aura AG LT feel secure and glide smoothly. The full peripheral frame is strong and rigid, which grants the pack’s impressive 40-lb (18.1-kg) load capacity. 

Aesthetic

⭐ STAR RATING: 4.5 / 5 stars

I’m a big fan of the Osprey Aura AG LT’s aesthetic. Its Antidote Purple color pairs beautifully with other common shades of outdoor apparel. This applies to the Koseret Darjeeling Spring Green color, too. 

Both options also have complementary tones throughout the pack, adding visual interest. If you like simplicity and versatility, the pack is available in black, too. Though even on the black version, the Osprey Aura AG LT has various textures. The honeycomb material has a slight gloss, and the fabric-reinforced pockets have a similar sheen. 

Overall, it looks sleek and put together, except for one pesky feature. While most straps have places to tuck in excess, this isn’t the case for the hip belt compression straps. These seem longer than necessary and take away from the seamless look. 

Warranty

⭐ STAR RATING: 5 / 5 stars

I’ve come across very few companies with warranties that compare to Osprey’s and have yet to find one more generous. Under its All Mighty Guarantee, Osprey “will repair any damage or defect for any reason free of charge.” If a functional repair can’t be made, the company will replace your pack.

This warranty applies no matter who purchased the pack, or when and where the purchase was made. Though its turn-around is a bit lengthy (currently 6-10 weeks), Osprey can expedite minor repairs by sending you a DIY kit. It”s easy to fix broken buckles or torn webbing this way. 

But, in my experience, breaks on Osprey packs don’t occur easily. I’ve never had to replace even minor parts in my 7+ years of owning Osprey products. If instances were to occur, though, it’s nice to know the company has my back — figuratively and literally. 

Value

⭐ STAR RATING: 5 / 5 stars

I think the Osprey Aura AG LT 65 comes at a very reasonable value. Its carry capacity is ideal for a multi-day, overnight backpacking trip. It’s constructed with high-quality materials and I appreciate its thoughtful technical features. Along with that, a rain cover is included. 

However, I knocked off a half star because $290 tops several similar packs’ prices. For example, one of its closest competitors is the Mountainsmith Apex 60, which costs $219.95.

The Maven 65 is closer in price at $279.95. But it weighs less and ranks better in the areas of organization and comfort.

function reportWindowSize() { let barContainer = document.querySelector(“#kb-progress-bar101312_e0f73e-4e”); let type = “line”; let barSvg = barContainer.querySelector(“svg”); if ( ! barSvg ) { return; } let barPaths = barSvg.querySelectorAll(“path”); let path1 = barPaths[0]; let path2 = barPaths[1]; let stokeWidths = [1.75,1.75,2]; if( window.innerWidth < 768 ) { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[2]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[2] / 2) + ” L 100,” + ( stokeWidths[2] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[2] / 2) + ” L 100,” + ( stokeWidths[2] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[2]); path2.setAttribute( “stroke-width”, stokeWidths[2]); } else if( window.innerWidth < 1025 ) { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[1]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[1] / 2) + ” L 100,” + ( stokeWidths[1] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[1] / 2) + ” L 100,” + ( stokeWidths[1] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[1]); path2.setAttribute( “stroke-width”, stokeWidths[1]); } else { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[0]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[0] / 2) + ” L 100,” + ( stokeWidths[0] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[0] / 2) + ” L 100,” + ( stokeWidths[0] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[0]); path2.setAttribute( “stroke-width”, stokeWidths[0]); } } window.onresize = reportWindowSize; var waitForProgressBar101312_e0f73e4e = setInterval(function () { if (typeof ProgressBar !== “undefined” ) { clearInterval(waitForProgressBar101312_e0f73e4e); let responsiveStrokeSizes = [1.75,1.75,2]; let initialStroke; if( window.innerWidth < 768 ) { initialStroke = responsiveStrokeSizes[2]; } else if( window.innerWidth < 1025 ) { initialStroke = responsiveStrokeSizes[1]; } else { initialStroke = responsiveStrokeSizes[0]; } let progressBar101312_e0f73e4e = new ProgressBar.Line(“#kb-progress-bar101312_e0f73e-4e”, { color: “#ffcc00”, trailColor: “var(–global-palette7, #EDF2F7)”, duration: “2000”, easing: “easeInOut”, strokeWidth: initialStroke, }); let progressBarController101312_e0f73e4e = new ScrollMagic.Controller(); let desiredAnimation = new ScrollMagic.Scene({triggerElement: “#kb-progress-bar101312_e0f73e-4e”}); desiredAnimation.triggerHook(0.88); desiredAnimation.addTo( progressBarController101312_e0f73e4e ); desiredAnimation.on(“start”, function (e) {progressBar101312_e0f73e4e.animate( 0.98 , { duration: 2000, step: function(state, bar) { let value = 0; let elementContainer = document.getElementById(“kb-progress-bar101312_e0f73e-4e”); let elementAbove = document.getElementById(“current-progress-above101312_e0f73e-4e”); let elementInside = document.getElementById(“current-progress-inside101312_e0f73e-4e”); let elementBelow = document.getElementById(“current-progress-below101312_e0f73e-4e”); if( false ) { value = Math.round(bar.value() * 100 ); } else { value = Math.round(bar.value() * 5); } value = bar.value() * 5; value = Math.round( value * 10) / 10;value = value.toFixed(1); if( elementAbove ){ elementAbove.innerHTML = “” + value + “%”; } else if ( elementInside ){ elementInside.innerHTML = “” + value + “%”; } else if ( elementBelow ){ elementBelow.innerHTML = “” + value + “%”; } elementContainer.setAttribute(“aria-valuenow”, value); } } , function(){} );});} }, 125);

Like everything about the Osprey Aura AG LT, but wish that the light version weighed even less? Check out the Osprey Eja / Exos in its 58L model. Its load capacity is more limited than the Aura AG LT — 35 lbs (15.9 kg) rather than 40 lbs (18.1 kg). Its volume is also more limited, totaling 55L.  

But the extra small/small size of the Eja weighs 41% less than the extra small/small Aura. At just 2.717 lbs (1.232 kg), it’s a dialed-in backpack that will complement the rest of your ultralight gear.

Plus, it has many of the same features, like an easy-to-use adjustable ladder system and a removable lid. Like all Osprey products, it also has an incredible lifetime warranty. Get all the details in my Osprey Eja backpack review.

Gregory Maven 65 / Paragon 68

function reportWindowSize() { let barContainer = document.querySelector(“#kb-progress-bar101312_7197aa-52”); let type = “line”; let barSvg = barContainer.querySelector(“svg”); if ( ! barSvg ) { return; } let barPaths = barSvg.querySelectorAll(“path”); let path1 = barPaths[0]; let path2 = barPaths[1]; let stokeWidths = [1.75,1.75,2]; if( window.innerWidth < 768 ) { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[2]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[2] / 2) + ” L 100,” + ( stokeWidths[2] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[2] / 2) + ” L 100,” + ( stokeWidths[2] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[2]); path2.setAttribute( “stroke-width”, stokeWidths[2]); } else if( window.innerWidth < 1025 ) { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[1]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[1] / 2) + ” L 100,” + ( stokeWidths[1] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[1] / 2) + ” L 100,” + ( stokeWidths[1] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[1]); path2.setAttribute( “stroke-width”, stokeWidths[1]); } else { if( type === “line” ){ barSvg.setAttribute( “viewBox”, “0 0 100 ” + stokeWidths[0]); path1.setAttribute( “d”, “M 0,” + ( stokeWidths[0] / 2) + ” L 100,” + ( stokeWidths[0] / 2)); path2.setAttribute( “d”, “M 0,” + ( stokeWidths[0] / 2) + ” L 100,” + ( stokeWidths[0] / 2)); } path1.setAttribute( “stroke-width”, stokeWidths[0]); path2.setAttribute( “stroke-width”, stokeWidths[0]); } } window.onresize = reportWindowSize; var waitForProgressBar101312_7197aa52 = setInterval(function () { if (typeof ProgressBar !== “undefined” ) { clearInterval(waitForProgressBar101312_7197aa52); let responsiveStrokeSizes = [1.75,1.75,2]; let initialStroke; if( window.innerWidth < 768 ) { initialStroke = responsiveStrokeSizes[2]; } else if( window.innerWidth < 1025 ) { initialStroke = responsiveStrokeSizes[1]; } else { initialStroke = responsiveStrokeSizes[0]; } let progressBar101312_7197aa52 = new ProgressBar.Line(“#kb-progress-bar101312_7197aa-52”, { color: “#ffcc00”, trailColor: “var(–global-palette7, #EDF2F7)”, duration: “2000”, easing: “easeInOut”, strokeWidth: initialStroke, }); let progressBarController101312_7197aa52 = new ScrollMagic.Controller(); let desiredAnimation = new ScrollMagic.Scene({triggerElement: “#kb-progress-bar101312_7197aa-52”}); desiredAnimation.triggerHook(0.88); desiredAnimation.addTo( progressBarController101312_7197aa52 ); desiredAnimation.on(“start”, function (e) {progressBar101312_7197aa52.animate( 0.98 , { duration: 2000, step: function(state, bar) { let value = 0; let elementContainer = document.getElementById(“kb-progress-bar101312_7197aa-52”); let elementAbove = document.getElementById(“current-progress-above101312_7197aa-52”); let elementInside = document.getElementById(“current-progress-inside101312_7197aa-52”); let elementBelow = document.getElementById(“current-progress-below101312_7197aa-52”); if( false ) { value = Math.round(bar.value() * 100 ); } else { value = Math.round(bar.value() * 5); } value = bar.value() * 5; value = Math.round( value * 10) / 10;value = value.toFixed(1); if( elementAbove ){ elementAbove.innerHTML = “” + value + “%”; } else if ( elementInside ){ elementInside.innerHTML = “” + value + “%”; } else if ( elementBelow ){ elementBelow.innerHTML = “” + value + “%”; } elementContainer.setAttribute(“aria-valuenow”, value); } } , function(){} );});} }, 125);

If your trip demands 65L of volume, but you really love organizational features, opt for the . This pack has a trekking pole attachment, hip belt pockets, and web attachment points. It also has an optional sleeping bag compartment, a “quickstow” system for sunglasses, and much more.

Despite all these features, the Maven 65 actually weighs less than the Osprey Aura AG LT 65. Its extra small/small size weighs 3.39 lbs (1.54 kg). The same size Aura clocks in at 3.837 lbs (1.740 kg). The Gregory Paragon, which is the brand’s men’s version, also weighs less than the Osprey Atmos.

FINAL VERDICT – Is The Osprey Aura AG LT Worth It?

The Osprey Aura AG LT is absolutely worth it. Its 63L volume and 40-lb (18.1-kg) load capacity make it an especially ideal pick for long multi-day treks. Its streamlined organization and customizable features allow you to tailor the pack to your needs. To further ensure a perfect fit, it’s available in gender-specific models and various sizes.   

Overall, the pack is built to last, being made with durable, water-resistant, and eco-friendly materials. Though, if damage were to occur, consumers have peace of mind given its generous lifetime warranty. It’s also a one-and-done purchase — no additional accessories are required. 

The comfort of this pack was called into question, with Skycie and I having differing experiences. To ensure the Osprey Aura AG LT fits properly, take it into your local REI store or closely follow the steps in this Osprey sizing guide.

I’d also recommend being conscious of how you pack your bag, along with the weight of your load. You can use a digital weight scale to ensure it”s no more than ~20% of your body weight. And lastly, make sure to test the Osprey Aura AG LT on shorter trails before heading out on a long excursion. 

By following these steps, you’ll be much more likely to have a positive experience, just as I did. Without question, I’d buy the Osprey Aura AG LT again and look forward to having it on my next big adventure!
