## Overview

The Osprey Exos 38 is a premium ultralight backpack designed for serious hikers and thru-hikers who demand comfort, durability, and smart organization. Featuring a 38-liter capacity, 2.69-pound weight, adjustable Airspeed suspension for a custom fit, and integrated hydration compatibility, it’s crafted from 100% recycled materials to combine sustainability with performance. Ideal for multi-day adventures where every ounce counts, the Exos 38 keeps you cool, organized, and ready to conquer the trail.

## Description

When every ounce matters but you still need a backpack that's more than just a sack with shoulder straps, the Exos makes for an excellent ultralight companion. The Exos 38, made of 100% recycled materials, is perfect for those more committing trips when resupply is few and far between. Highly experienced backpackers will appreciate industry-leading comfort and ventilation—without the weight it often adds—making it the perfect pack for committing thru-hikes and ultralights like the AT or Colorado Trail. Need to slim things down even further? Remove the floating lid and use the integrated FlapJacket to protect your gear inside. Plus, our refined AirSpeed suspension keeps you cool with maximum airflow between you and your pack, so each mile stays as comfortable as the last.

Review: One of the best... - @ 5'6" this pack is just perfect. Many adjustments for fine tuning. Also holds my 32oz stainless steel liquid container with added cook cup in the side pocket(s). My personal requirement.
Review: Osprey Exos FTW - This is an amazing backpack. I say that due to the comfort. I have other lightweight or ultralight backpacks such as Mountain Laurel Designs Prophet 48L and the Hyperlite Mountain Gear Waypoint but neither of those backpacks match the comfort of the Osprey Exos. I thru hiked the Appalachian Trail starting with an Exos 48 then switched to the lighter Osprey Levity but although the Levity was a great backpack, it did not match the comfort of the Exos. Having dialed in my gear, I bought this 35L Exos because I didn't need the additional space and weight of a 45L backpack. The 35L Exos is plenty big enough for me to carry 4-5 days of food even without the top brain pouch. Without the top brain pouch, the weight comes in at 38oz. It's a full pound heavier than my Prophet and pretty close to the weight of a UL Hyperlite Mountain Gear Southwest but the comfort and suspension system is worth it and if I need to carry additional weight, this backpack can handle the load whereas my other lighter packs would struggle and my shoulders get very angry at me after about 15 miles. The warranty on the Ospreys is another selling point. After thru hiking the AT, I sent my Osprey Levity back for repairs and the sent me a brand new Levity backpack free of charge.
