The innovative suspension system of the Paragon 58 internal frame backpack allows it to comfortably carry up to 50 pounds and stow 3539 cubic inches of gear at a weight well below that of its load-hauling peers. Adding value and functionality, Enwild includes a 3D Hydro Reservoir.


The innovative suspension system of the Paragon 58 internal frame backpack allows it to comfortably carry up to 50 pounds and stow 3539 cubic inches of gear at a weight well below that of its load-hauling peers. Adding value and functionality, Enwild includes a 3D Hydro Reservoir.

Equipped with Gregory’s Aerolon suspension system, the pack employs an ultra-lightweight hollow 7001 aluminum frame and a mesh-encased, die-cut foam backpanel to offer excellent load stabilization and ventilated performance. Adjustability in the harness and hipbelt allow you to customize fit. Load lifter straps and an adjustable sternum strap further enhance fit and ensure stability. Siliconized padding in the lumbar portion of the pack increases comfort and aids in load transfer. To ensure a customized fit, the pack is available in Small/Medium (fits torso sizes ranging from 15”-19”) and Medium/Large (18”-22”) size options.

The top-loading main compartment of the pack has an extendible drawstring closure. A zippered front entry allows access to a separate, lower sleeping bag compartment. A large front stuff pocket provides a place to keep discarded layers or other gear easily accessible. Zippered lid pockets and zippered hipbelt pockets offer additional organizational options. Side compression straps allow you to cinch down the packbag to keep the contents of the pack stabilized and they double as external lash points.

Other features include large side stretch water bottle pockets, trekking pole attachments, a front harness quick-stow feature for sunglasses, and an included raincover. An integrated sleeve and exit port make the pack hydration compatible (3D Hydro Reservoir included). That same sleeve can be removed entirely and, thanks to its integrated minimalist shoulder strap, it can be used as a lightweight daypack or summit pack!

The Gregory Paragon 58 internal frame backpack is available in your choice of size and color options.

Very light, versatile pack for a 3 to 4 day hike. Excellent quality material and fit.


Flexibility, adjustments for proper fit and light weight


The shoulder adjustment straps are sometimes difficult to locate.

Light Pack


Just took this pack on a 3 day backpacking trip in Yosemite and it was super comfortable. The suspension system made the weight of my pack disappear.

Great pack - great fit


Adjustable fit. Included day pack and hydration system. Great value.


So far, nothing!

Hsing-o L.


A great Lightweight option.


I love the new ventilation system that allows better air flow and prevents a sweet back. It fits like a glove and has easy access to your gear with ample pockets.



Matt T.


Seems designed to concentrate weight on lumbar


Weight Suspension was very good Great value with rain fly and reservoir


Should have 3 sizes M/L was too long for me (18 inch torso) Tried S/M but still had pressure point in lumbar. Lumbar is overbuilt but I rather distribute the weight more evenly.

Great pack, highly recommend


took this pack to the Grand Canyon for a week. I carried 30 lbs on my back and barely felt it. The pack is very adjustable, which came in handy when I wanted to shift the weight up, down, or closer to my back. The aerolon suspension did an excellent job of shifting the weight to my back and hips and off of my shoulders. You can loosen all the straps and undo the hip belt and the pack still sits on your hips thanks to the grip on the lumbar support. The day pack/hydration sleeve is great once you get to camp and just want to hike around and check out the scenery without lugging an entire pack around. Haven't had a need for the rain cover yet but it's nice that they include it.


I carry water bottles not a bladder. The right side mesh pocket has a front entrance to make water bottle retrieval easier without removing the pack. It's easy to retrieve but sometimes difficult to get the bottle back in. This is certainly not an issue worth taking a star off for and not an issue at all if you like to carry s bladder.

Great weekend pack


This pack has a ton of features and plenty of space for long weekend trips. Comes with a summit bag that acts as storage for the hydration bladder. The suspension is well designed and comfortable carrying loads. My weekend packout with food, water and gear runs about 34 pounds but felt lighter and stayed in place thanks to the design of padding and hip belt.


Webbing and straps could be a little sturdier, no issues but worried about wear and them holding up over time.



Paragon 58


Just finished a 200 mile section hike of the AT with this pack and loved the pack. Tried lighter fixed torso packs but found I fall in between sizes. Ended taking this pack because it provided torso adjustment to specifically fit me as well as adjustment to the ample belt pouches. Great hip belt with good lumbar padding, and a well ventilated back panel. This pack makes load carrying comfortable. An extra pound for this pack over more lightweight packs is worth it, because it makes the hike more comfortable.


Mesh side and back pockets easily damaged. Surprised to find tears and rips without any known impacts.

Edward R.


Good pack


This pack was very comfortable overall. Carried my gear well. Have only taken it out once on a 10 mile out and back trip. The mesh side pockets can hold a lot of items. Easy to adjust to get a good fit. Looking forward to taking it out again soon. Love the color as well.


Didn’t seem to breathe as much as I hoped. My back was still pretty sweaty, but it was also 100% humidity on my trip, so not sure how much was sweat was inevitable due to the weather. More tests needed. The side water bottle pocket can be hard to access at times.



Comfortable Backpack


I’ve had Osprey packs over the past 20 years. They have never been that comfortable, but I stuck with them because I knew of their quality. Decided to make a change due to the weight of the Paragon 58. So glad that I did, it’s probably the most comfortable pack I’ve owned.


Hard to find anything I don’t like about it. The side pockets and the hipbelt pockets could be a little larger.



Could not be happier. Took it out of the box on Thursday, hiked with it on Friday. Needed no adjustment. Carries weight well; weight distribution beautifully perfection. Has all the core requirements and lots of unique accessories. So, so, so Versatile


Out the box comfort. Has adjustments. May not need them. Comes with both the Hydro Reservoir and the Rain Cover. Tough material. Very versatile. Many uses. Distributes weight perfectly


At this price, absolutely none. Has my name in it. No faults.



Lightweight and comfortable pack.


Lightweight Carries up to 50lbs comfortably


Thin hardware and straps, possible durability issues.
