Product details:

Hyperlite optimized this minimalist, indestructible day backpack for those passionate alpinists, backpackers, thru hikers and other goal-oriented adventurers who are extra hard on their gear. This Summit Pack utilizes a fully woven Dyneema fabric, which is 100% waterproof, bombproof and foolproof. This pack was designed to be used. Hard. It combines the minimalist elements of the Hyperlite urban Metro Pack with the functional basic daisy chains and optional Stuff Pocket of Hyperlite 4400 Porter pack. It compacts enough to be stowed away in a larger pack, yet it's roomy enough to securely hold enough water, food, extra gear and clothing for your big day. Stripped down, dialed in; this pack is exactly what the most hardcore adventurer needs and nothing more.
