Product Details
Whether you need a daypack, a summit bag, or just a hydration sleeve to insulate the reservoir in your main pack, the CamelBak Arete™ 18 Backpack has you covered. Normally a lightweight bag with an impressive 18 liters of space for anything you think you'll need on the trail, it also folds in on itself for easier storage inside the main pack for use as a summit bag when you don't need to bring all your gear on a side hike. But it still serves a purpose folded up in your pack, as it's the perfect way to insulate and protect the included 1.5L Crux™ Reservoir and keep yourself hydrated on the trail.
