Ideal for fast-and-light thru-hikes or lightweight backpacking, the Osprey Exos 58 pack offers tons of storage capacity, comfortably carries up to 40 pounds, but weights well under 3 pounds!
An ultra-lightweight 6065 aluminum frame combines with a 3D tensioned breathable mesh backpanel to equip the pack with support and ventilation. Seamless layered mesh on the Exoform shoulder harness and hipbelt provides comfortable padding at minimal weight. Further enhancing fit, the hipbelt utilizes an ErgoPull closure that draws tension along the top and the bottom of the belt. An adjustable sternum strap and load-lifter straps allow you to make on-the-go fine-tuning.
Accommodating users of different dimensions, the pack is available in three sizes: Small best fits torsos ranging from 16"-19" in length, Medium accommodates torsos ranging from 18"-21", and the Large best fits 20"-23" torso lengths. The storage capacity varies based on size, as well: Small offers 3356 cubic inches, Medium provides 3539 cubic inches, and the Large has a 3722 cubic inch capacity.
The top-loading packbag is accessed through a removable, floating lid with dual zippered pockets. An integrated FlapJacket panel protects the main packbag if and when you aren't using the top lid. Stretch mesh pockets on the front and sides offer additional organizational options and keep gear and extra layers close at hand. A small dedicated stretch pocket on the shoulder strap is perfect for snacks, energy gels, or small electronics. Removable side compression straps aid in load transfer and allow you to cinch contents safely in place. Other features include an ice tool attachment loop, cord tie-off points, a small safety whistle integrated into the sternum strap buckle, and integrated, removable straps for lashing a sleeping pad. The pack is hydration system compatible (hydration system sold separately).

Real Customer Reviews
- A well-rounded model, comfortable and lightweight
Likes: We are just getting into camping and we see ourselves as casual hikers. We were looking for a pack that offers support but not a overkill for the length of our trips (3-4 days) and the weight we'd carry (30lbs tops for this pack, plus a smaller, regular pack for other stuff). We tried on several models at a local store, and Osprey offers the best support. We were choosing between the Atoms AG65 and this one. While the AG65 hip belt is very supportive, the pack also weighs much more. Many people find the hip pockets on AG65 as a huge plus, however my husband, who will be the main carrier of this pack, find those hip pockets getting in the way of his arms while walking and actually prefers the Exos 58's slimmer belt design. Since we don't foresee ourselves carry more than 30lbs usually, we felt this pack fits our trips well.
Dislikes: We haven't used it on a trip yet, so nothing to dislike so far. Hope it stays this way!
- Light-Weight but Holds Everything!
Likes: Light-weight, can hold a lot
- Great Backpack
Likes: Number one like is definitely the weight. It's so nice to start out a few pounds ahead. The materials of the pack are quality too.
Dislikes: You have to understand the limitations of the pack and not pack too heavy. Overall, I recommend the pack and really enjoy it.
- Superior comfort, but leaves features to be desired.
Likes: The back panel breathes incredibly well and fits comfortably.
Dislikes: No hipbelt pockets. This wouldn’t be so bad if Osprey offered aftermarket hipbelt/shoulder pockets. I get wanting to cut weight but I found the lack of hipbelt pockets to be a pain on the trail.
- Love Osprey, but not this pack
Likes: Love the colors, the broad mesh back panel, and the weight. This pack is definitely designed for the minimalist.
Dislikes: I believe this pack to be very polarizing. Unfortunately, this will not be one of my go to packs. No hip belt pockets was a bigger deal to me than I realized. Osprey-please bring these back!
- Great pack so far
Likes: Haven't had it on the trail officially, but did use as my only container while car camping. I love the pockets and there seems to be a great deal of space. Feels like it really hugs my back and the ventilating mesh is nice.
Dislikes: Disappointed that they dropped the hip belt pockets. Guess I'll have to go to a different manufacturer for an add on. It's my problem, not the pack's, but I can't figure out how to get a water bottle in and out of the side pocket without taking the pack off
- Ultralight option with plenty of room for extended trips.
Likes: Bought this to round out my ultralight kit for 5+ day trips. My Atmos 65 is definitely more comfortable, but the Exos is significantly lighter. The 48l is probably enough for a solid UL setup but I went with the 58 because it holds a Bearvault BV500 horizontally and the brain is easily removed to lose a few unnecessary ounces. Compression straps are thin to shed weight but plenty strong.
Dislikes: The suspension isn't as comfortable as the Atmos AG; Hip belt doesn't grip the waist in the same way and lacks pockets. No sleeping bag compartment.
- Lives up to its promises
Likes: -Perfect for hikers like me who are transitioning to ultralight or lighter loads
-On point: weight + comfort + price + durability
-Really like the thin straps; features don’t overwhelm me. I prefer simple packs with one big pocket and few extras
-Mesh pockets are very versatile and easy access feature is on point
-Trekking poles stow on the go system is very appreciated
Dislikes: -No hipbelt pockets? Come on! Who doesn’t use hipbelt pockets??
-I would have loved some waterproof material for the major compartment
