Ultralight Stuff 18L Backpack

Osprey's Ultralight Stuff Pack has the room you need for a day's worth of gear whether you're hiking, multipitch climbing, or traveling across foreign cities. Stow the Ultralight Stuff Pack inside itself and pack it up in bigger climbing packs, then take it out after the approach and when it's time to ascend the hundreds of feet above you. The air mesh back panel uses minimal padding and breathable fabrics to keep your back comfy throughout. There's a top zippered stash pocket for valuables, and a stretch side pocket for water bottles.
