Comfort/Fit
The Exos 58 provides good overall comfort for an ultra-light pack and performs well when carrying loads under 30 pounds. The padding on the Exos 58 is much better than the previous model and the pack still has the easy adjustment options and suspension system of previous models.
The Exos 58 hip belt has a wrap around fit and provides good padding. The Exoform hip belt is comfortable and very breathable. Two large zippered pockets on the hip belt provide good storage options.
The Osprey Exos 58, armed with the trampoline back panel and curved frame, vented very well in testing. The shoulder straps have more padding than the previous Exos 58 model and the Exoform harness is also more comfortable and breathable than the previous model. There is also a small storage pocket on each side of the harness.
Storage
The Osprey Exos 58 provides top loading access to the main compartment via a traditional storm flap feature. However, the Exos does not provide secondary access to the main compartment. The Exos does have a large stretch pocket on the rear outside of the pack that is good for storing rain gear, wet items or other things that you might need to access quickly.
The Exos 58 comes with two zippered hip-belt pockets, but they are smaller than some other packs. I had a hard time storing my phone, a GPS, and/or larger snack items. The pockets were large enough to store a small bar or other very small items.
The lid on the Exos 58 has a top storage pocket but the zipper is not very long. This makes access difficult and it is not big enough for a helmet. There is a second zippered mesh pocket on the underside of the lid that is large enough to store flat items such as maps and other small essentials. You can also remove the lid of the Exos and protect the top of the pack with the Flapjack closure system.
The Exos 58 comes with a stretch mesh side pocket on each side of the pack that can be used to store water bottles or other items needed for quick access. The side stretch pockets have dual access to store the bottle from the top or at an angle to allow for easier access when on the move.
The Exos 58 has an internal hydration sleeve that accommodates up to a 3-liter hydration bladder. There is also a small pocket (on each side of the harness) that is large enough for a bar or small camera.
Stability
The Osprey Exos 58 felt stable when carrying loads in the 20-30 pound range, but I felt like I was pushing the limits of the pack when carrying over 30 pounds. With loads under 30 pounds, the Exos was comfortable and did not shift or float regardless of the terrain.
Durability
The Exos 58 proved durable despite its ultra-light feel and materials. The zippers, pockets and fabrics all performed well and showed no signs of damage or wear after extended use with the exception of a small tear in the rear stretch pocket.
The Verdict
The redesigned (2014) Osprey Exos backpack is an ultra-light backpack that provides good comfort and has numerous features for traveling light and fast on the trail.
