Osprey Exos 38L Ultralight Backpack – Men's, Dark Charcoal, L/XL

Meet the Osprey Exos 38L: Ultralight, Durable, and Ready for Remote Trails

On backcountry journeys where weight matters as much as capacity, the Exos 38L delivers a featherweight footprint with a surprisingly capable feature set. Made with 100% recycled materials, this pack emphasizes sustainability without sacrificing rugged reliability. Its compact frame is designed to ride close to your body, helping you conserve energy mile after mile.

Lightweight comfort starts with the AirSpeed suspension. The injection-molded ladder system allows 4 inches of torso adjustability, so you can tailor the balance and airflow to your torso length. The result is steady load transfer and a cool feel between you and your pack, even on warm climbs.

Smart storage and versatile setup

Two hipbelt pockets keep small items within reach, ideal for a map, snacks, or a phone without slowing your pace. Inside, a hydration sleeve with a center back hose port keeps water accessible without rattling on rough trails. The floating lid is removable, and there are top- and under-lid pockets for stashing essentials — and if you want to trim weight further, you can rely on the integrated FlapJacket to protect gear inside without the lid.

Durability matters on remote routes, and the Exos 38L rises to the challenge with a sturdy backpanel mesh and durable main fabrics that resist wear and keep your load secure over multiple seasons.
