Gregory Maven 55 Review (I Tested it in the Wild)

function reportWindowSize() { let barContainer = document.querySelector(“#kb-progress-bar98848_7e2633-1d”); 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 waitForProgressBar98848_7e26331d = setInterval(function () { if (typeof ProgressBar !== “undefined” ) { clearInterval(waitForProgressBar98848_7e26331d); 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 progressBar98848_7e26331d = new ProgressBar.Line(“#kb-progress-bar98848_7e2633-1d”, { color: “#ffcc00”, trailColor: “var(–global-palette7, #EDF2F7)”, duration: “2000”, easing: “easeInOut”, strokeWidth: initialStroke, }); let progressBarController98848_7e26331d = new ScrollMagic.Controller(); let desiredAnimation = new ScrollMagic.Scene({triggerElement: “#kb-progress-bar98848_7e2633-1d”}); desiredAnimation.triggerHook(0.88); desiredAnimation.addTo( progressBarController98848_7e26331d ); desiredAnimation.on(“start”, function (e) {progressBar98848_7e26331d.animate( 0.98 , { duration: 2000, step: function(state, bar) { let value = 0; let elementContainer = document.getElementById(“kb-progress-bar98848_7e2633-1d”); let elementAbove = document.getElementById(“current-progress-above98848_7e2633-1d”); let elementInside = document.getElementById(“current-progress-inside98848_7e2633-1d”); let elementBelow = document.getElementById(“current-progress-below98848_7e2633-1d”); 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);

Gregory Maven is best for:

• Various types of backpacking trips 
• A wide range of body types 
• Those who love to stay organized 

Gregory Maven might not be a fit for:

• Budget hikers
• Those seeking the industry’s most eco-friendly products

All things considered, I’ve rated the Gregory Maven 4.9 out of 5 stars overall. Amazingly, the Gregory Maven can carry up to 50 lbs (22.7 kg) despite its extra small/small size weighing just 3.31 lbs (1.5 kg).

Along with various sizes, this lightweight pack is available in a men’s version: the Gregory Paragon.

Both Gregory Maven models come in multiple capacities: 45L, 55L, and 65L. For this review, Skycie and I tested the 55L pack and found it to be ideal for all types of backpacking trips. It’s very comfortable and breathable, and we really loved its extensive organizational features. Several pockets, compression straps, and more are found throughout the pack.

The Gregory Maven’s materials and hardware are highly durable, and I appreciate the included rain cover. I’m also a fan of the hiking pack’s overall aesthetic and customization abilities. This includes an optional sleeping bag compartment and a removable lid. 

I have very little negative feedback for the Gregory Maven / Paragon series. But my largest qualm relates to its adjustable waist. On one hand, it holds in place and supports load transfer for a variety of body types. But on the other hand, its maneuverability could be greatly improved. 

Word to the wise: don’t extend the belt further than necessary, because reverting this is a frustrating process. 

In addition, I wish that Gregory used more recycled materials to complement the pack’s 40% post-consumer lining. 

But remember, it’s my job to be critical when writing these reviews. Though there may be some areas for improvement, don’t get me wrong — I love the Gregory Maven. It’s one of my favorite backpacking packs I have tested!

Gregory Maven Features Review

Alright, that was the quick summary! Now, I’ll go into every detail found on the Gregory Maven. By the end of this section, you’ll know exactly what to expect from this backpacking pack! 

Below, I extensively cover each of the following Gregory Maven features. If you have a burning question, click these links to jump ahead:

Size

⭐ STAR RATING: 5 / 5 stars

The extra small/small Gregory Maven has a volume of 52L. But perhaps you’re wondering, how is that volume dispersed throughout the pack? 

To determine this, I took inspiration from ASTM International’s standardized test. This involved filling each compartment with as many golf balls as possible. Estimating that there are roughly 12 golf balls per liter, here are my findings:

• Hip belt pockets (2x) – 9 golf balls / 0.75L per 
• Side pockets (2x) – 30 golf balls / 2.5L per
• Front pocket – 52 golf balls / 4.3L 
• Lid (accounting for both external and internal access) – 100 golf balls / 8.3L 
• Main compartment – 395 golf balls / 32.9L 

Completing this test made me realize how well-balanced the Gregory Maven pack is. Every piece of gear has a size-appropriate home, while competing packs often have large, undedicated spaces. For more comparative insight, see the chart on our backpacking pack round-up.

Weight

⭐ STAR RATING: 5 / 5 stars

Unloaded, the extra small/small size of the Gregory Maven 55 weighs an impressive 3.31 lbs (1.5 kg). The small/medium size weighs very closely at 3.41 lbs (1.55 kg) but grants an extra three liters of storage. All models mirror this lightweight quality; see the Technical Specifications section for details. 

When testing the Gregory Maven, Skycie’s pack weight totaled 20.5 lbs (9.3 kg). This suited her petite size, but note that the backpack has a max carry capacity of 50 lbs (22.7 kg). This weight-to-carry ratio beats out nearly all other packs we tested! 

👉 Want the Best Weight-To-Carry Ratio? Among the backpacking packs I tested, the Hyperlite 3400 Southwest has the best weight-to-carry ratio. At 2.2 lbs (0.979 kg) and with the ability to carry up to 40 lbs (18.1 kg), it’s the only one that tops this Gregory backpack. 

Height Adjustable

⭐ STAR RATING: 5 / 5 stars

Most backpacking packs have an adjustable torso length feature, but not all are user-friendly. Fortunately, the Gregory Maven makes customization simple. The hook-and-loop panel is easy to detach, yet feels highly secure once modified. I also like that markings indicate sizes, assisting those who are unsure whether to move the panel higher or lower. 

Torso adjustability, along with gender-specific models in multiple sizes, helps ensure a perfect fit. This influences not only comfort but pack aesthetics. 

Waist Adjustable

⭐ STAR RATING: 3 / 5 stars

Using compression straps, all technical hiking packs allow you to adjust the hip belt fit to some extent. But the Gregory Maven is rare in that it has an extendable hip belt. It caters to waists measuring 24 – 46 inches (61 – 116.8 cm). Truly, I love the innovation and inclusivity.  

However, when it comes to functionality, I’m disappointed in this feature. It functions similarly to the adjustable back panel, having a hook-and-loop fastener. You can use your fingers to pry this strip back and tug on the compression strap to get the panel to extend easily enough. 

But getting the panel to revert? Good luck. With patience and persistence, I eventually got the hip belt back to its smallest size. I f using this feature, I would highly suggest extending the belt only slightly. Try it on, and continue extending as needed. But avoid overextending to save yourself quite a bit of hassle.  

Comfort 

⭐ STAR RATING: 5 / 5 stars

As mentioned above, this pack’s various sizes and adjustable features create a near-custom fit. Standing five feet tall, I fall outside the standard female build, and “one size fits all” packs are seldom suitable. But given these qualities, I found the Gregory Maven to be highly comfortable. 

Other features that contribute to comfort include generously padded shoulder straps. The same can be said of the adjustable hip belt and back panel. In addition, these padded areas are made with perforated foam, granting breathability. 

As far as suspension, the Gregory Maven has a proprietary FreeFloat system. Its frame is designed to support your natural movements when hiking. This prevents pressure on your hip bones, shoulder blades, and so forth.

To clarify, Skycie and I found this pack to be highly comfortable when carrying moderate loads. If you carry more without regard to your abilities, and especially if you exceed its 50-lb (22.7-kg) maximum, you may experience discomfort. Improper packing may also cause issues. 

Internal Organization

⭐ STAR RATING: 5 / 5 stars

The Gregory Maven has the best organization features of all other backpacking packs I tested. Its main compartment has a dedicated sleeping bag section. But for those that prefer spaciousness, its toggle buttons allow this feature to be optional. 

In addition, the main compartment has a hydration sleeve. Though its hook is intended for Gregory-brand reservoirs, I appreciate its versatile lower loop. One could easily attach a carabiner here to accommodate a variety of reservoir styles.

Draw the reservoir hose through a port found on the center of the back panel. While such an entry is common, the Gregory Maven stands out in the area of accessibility. 

It’s not only top-loaded but features bottom and side access via a full-length zipper. No other backpack I’ve ever come across makes reaching your gear so effortless. 

External Organization 

⭐ STAR RATING: 5 / 5 stars

The Gregory Maven impresses with not only its internal organization but also its external features. At its base, you’ll find compression straps with side-release buckles. These work well for bulky and/or heavier items, like a bear canister, sleeping pad, or tent — like the Big Agnes tent pictured here. 

Looking at the front face of the pack, there’s also an adjustable attachment loop on the bottom-right side. This is intended for an ice axe or trekking poles. Secure this type of gear further with the shock lock placed just above the loop. 

The front mesh pocket is wide and versatile. A strap and buckle at its mouth help to secure whatever gear you store here. 

Its side pockets are similar, made with a stretchy mesh that grants versatility. The right pocket has top and side access, which allows you to reach a water bottle without removing the pack. Both side pockets also have compression straps which allow you to secure extra gear, especially taller items. 

Compared to other backpacking packs, I found the two hip belt pockets to be on the smaller side. Unfortunately, I was unable to store my Otterbox-protected iPhone here. But these pockets are ideal for holding trail snacks, sunscreen, and other small items you want quick access to. 

Speaking of easy access, I love the sunglasses “Quickstow” system. It’s one of the pack’s most unique organizational features. To use it, tuck one arm of your sunglasses into the small shoulder strap loop. Then, extend the lower elastic band up and over your eyewear to hold it in place.  

The pack’s removable lid has two separate compartments

In addition, the lid of the pack is removable, ideal when you want to cut weight. Conveniently, the front two attachment points have side-release buckles. Though, the back three attachment points are ladder lock sliders with straps. 

In my opinion, side-release buckles on all attachment points (as seen on the REI Co-Op Flash 55) would have been more streamlined. But still, I appreciate the ability to adjust the pack to your carry needs.

When the lid is in use, it’s ideal for small, lightweight items, such as the Black Diamond headlamp pictured above. It also features gear lash points for external storage, as well as an internal zipper. This separate compartment has a key clip, as well as the pack’s included rain jacket. 

Rain Cover 

⭐ STAR RATING: 5 / 5 stars

The lid’s internal zippered pocket stores the pack’s included rain cover. It’s sized for the bag and features elastic around its edge, creating a secure, waterproof fit. The rain jacket is also the same Rosewood Red color as the pack, and I’m a fan of the put-together look. 

Materials 

⭐ STAR RATING: 4.5 / 5 stars

The pack body is made with 100D and 210D high-density nylon. The pack bottom is similar, being a 420D high-density nylon.

“D” refers to the denier, or the thickness, of the fabric. The higher the number, the thicker the material. Given the frequency your pack will contact the ground, the more durable base is a smart feature. During testing, Skycie placed this on sharp rocks and ice frequently without any issue. 

High-density nylon is a synthetic fabric that’s lightweight, durable, and water-resistant. Though unadvertised, you can tell by the pack’s grid and diamond patterns that it’s also sewn with a ripstop quality. This means that if a tear were to occur, it would likely stop at the source, rather than continue along the seam. 

In addition, the pack interior is lined with 40% post-consumer recycled 135D polyester. I appreciate this eco-conscious effort on Gregory’s part. But I did knock off a half-star because when it comes to backpacking materials, there’s some stiff competition. 

🌎 Eco-Conscious Packs: If you’re seeking some of the outdoor industry’s most eco-friendly backpacking packs, I have a few suggestions. Check out the REI Co-Op Flash 55,Osprey Eja / Exos, and Osprey Aura / Atmos. All are 100% made with recycled materials.

Hardware

⭐ STAR RATING: 5 / 5 stars

All hardware on the Gregory Maven is built to last. I find that the buckles function smoothly and latch securely. The same applies to the strap sliders and cord lock on the main compartment’s drawstring. The hydration reservoir hook and trekking pole shock lock also perform well, even when exposed to weight and pressure. 

The sternum strap whistle functions appropriately and is a nice safety feature to have easily accessible. So far, the metal zippers on the lid and hip belt glide as they should, too.  

Aesthetic  

⭐ STAR RATING: 5 / 5 stars

Aesthetics are always subjective, but in my opinion, the Gregory Maven is a stylish pack. I love its Rosewood Red version, having varying maroon tones, textures, and subtle patterns. Dusty pink straps and gray accents add further contrast. 

I’m also a fan of the metallic logo embellishments. This reflective element complements the diamond grid seen on the pack face. I also appreciate the matching rain jacket and overall, the brand’s attention to detail. 

If maroon isn’t your favorite shade, good news — the pack is also available in other colors. These vary by size but include Helium Grey and Spectrum Blue. The men’s Paragon is also available in Burnt Olive, Graphite Blue, Ferrous Orange, and Smoke Grey. 

Warranty 

⭐ STAR RATING: 5 / 5 stars

Overall, I love Gregory’s generous warranty. The brand states, “We guarantee that this product will be free from defects in workmanship and materials for as long as you own it.”

The Gregory Lifetime Guarantee has been around since 1996 — it’s not a gimmicky new promotion. For decades, the company has stood by its commitment to quality, and its warranty exclusions are very fair. Specifically, Gregory says, “We cannot cover damage due to unreasonable or abusive use, improper cleaning or storage, or normal wear and tear.” 

But even if your Gregory backpack experiences these types of damages, the brand will repair the pack for a “nominal” fee. Again, I find this to be generous, as well as an eco-friendly effort. The company will also send you easy-to-replace parts for you to DIY, which can help expedite the repair process.  

Value

⭐ STAR RATING: 5 / 5 stars

In my opinion, the Gregory Maven 55 / Paragon 58 is a great value. Its rain cover and various organizational features require no additional accessories. When it comes to load capacity, no other comparable pack beats its $259.95 price point — except for one.

The Mountainsmith Apex 60 has a max carry capacity of 60 lbs (27.2 kg). It can also be extended to 70L of volume, and it costs just $219.95. However, it’s only available in a singular size. So, while more affordable than the Maven and Paragon, it’s not nearly as accommodating to various body types.

Gregory Maven Alternatives

If you still have a few concerns after reading my Gregory Maven review, no worries. 

These alternatives, which I’ve personally tested as part of my ranking of the best backpacking packs, may better fit your needs:

REI Co-Op Flash 55 

function reportWindowSize() { let barContainer = document.querySelector(“#kb-progress-bar98848_4c74c9-6a”); 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 waitForProgressBar98848_4c74c96a = setInterval(function () { if (typeof ProgressBar !== “undefined” ) { clearInterval(waitForProgressBar98848_4c74c96a); 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 progressBar98848_4c74c96a = new ProgressBar.Line(“#kb-progress-bar98848_4c74c9-6a”, { color: “#ffcc00”, trailColor: “var(–global-palette7, #EDF2F7)”, duration: “2000”, easing: “easeInOut”, strokeWidth: initialStroke, }); let progressBarController98848_4c74c96a = new ScrollMagic.Controller(); let desiredAnimation = new ScrollMagic.Scene({triggerElement: “#kb-progress-bar98848_4c74c9-6a”}); desiredAnimation.triggerHook(0.88); desiredAnimation.addTo( progressBarController98848_4c74c96a ); desiredAnimation.on(“start”, function (e) {progressBar98848_4c74c96a.animate( 0.96 , { duration: 2000, step: function(state, bar) { let value = 0; let elementContainer = document.getElementById(“kb-progress-bar98848_4c74c9-6a”); let elementAbove = document.getElementById(“current-progress-above98848_4c74c9-6a”); let elementInside = document.getElementById(“current-progress-inside98848_4c74c9-6a”); let elementBelow = document.getElementById(“current-progress-below98848_4c74c9-6a”); 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);

Based on comparable products, the Gregory Maven 55 comes at a good value. But if a $200 price point is closer to your budget, check out the REI Co-Op Flash 55.

As I share in my REI Flash 55 review, this pack is very similar to the Gregory Maven / Paragon. It”s available in multiple sizes and gender-specific models, resulting in a highly comfortable fit. It has many organizational features, along with 55L of volume. Though, you can easily customize the pack to your carry needs with several modification options.

Note that while water-resistant, the REI Co-Op Flash 55 does not come with a rain cover. But if you already have one and a 30-lb (13.6-lb) capacity suits you, this pack could cut your expense by nearly 25%.

Gregory is, by no means, a brand that ignores eco-consciousness. It also has several admirable goals to improve in this area. But one of its major competitors has already addressed some of them: Osprey. 

If you want one of the most eco-friendly packs on the market, but the Gregory Maven isn’t quite right for you, consider the Osprey Eja / Exos. This durable, lightweight pack is completely made with recycled nylon ripstop fabric. Comparatively, the Maven and Paragon do not use recycled nylon, and their lining is 40% post-consumer material.

In addition, the Osprey Eja / Exos uses a PFC / PFAS-free DWR (durable water repellent). The brand also abides by the bluesign® Restricted Substances List. This eliminates and minimizes the use of environmentally harmful chemicals during manufacturing. When it comes to its hardware, Gregory plans to make this shift by 2025. 

Outside of environmental factors, the packs are very similar. Enjoy a near-custom, comfortable fit, and up to 58L of volume. A rain cover is not included and the Osprey Eja / Exos has a max carry capacity of 35 lbs (15.9 kg). But it”s a highly functional pack that suits a variety of preferences.

After extensive tests in real-world conditions, I can say with certainty that the Gregory Maven is worth it. 

The Gregory Maven’s weight-to-carry ratio is astonishing, suitable for short trips and long thru-hikes. Its included rain cover makes it a one-and-done kit, and undoubtedly, it’s built to last. I absolutely love the pack’s thoughtful organization and customizable features. 

Even though its waist adjuster could be more user-friendly, I appreciate the inclusivity. With an adjustable height, gender-specific models, and several sizes, this pack grants comfort to many body types. 

I wish that Gregory had used more eco-friendly materials when constructing this pack. But I look forward to seeing the brand accomplish its admirable goals outlined on its Sustainability page. And, I look forward to using the Gregory Maven many more times this season! It’s one I’ll be pulling from my gear rack often.
