"Patagonia asks which would you rather wrestle with: a pack you have to remove strap by strap, then try to hold or put down, while you reach around inside for what you need? Or, an anatomical design that swings around from back to front and lets you just reach inside, even with both hands. Large main compartment (coated with waterproof membrane) snugs closed with drawstring, hides under protective clamshell top flap. Oversized hidden pocket is the perfect place for travel documents. Mesh external ""chest"" pocket stores cap or gloves; zipper-closing pocket in top flap holds cellphone, camera and GPS (Global Positioning System). Reflective safety trim aids visibility. Mesh inside shoulder strap aids ventilation; zip-closing pocket in strap stores car keys or sunscreen. Waist strap buckles in place for easier carrying. Ballistic nylon. 12x14 1/2"", 600 cu.in. Weight 1lb 1oz. Closeouts. USA.View all Patagonia items."
