This cleanly designed daypack holds just what you need to hit the trail or the bike path. Its single compartment accommodates reading materials, lunch and jacket, and its raised, padded sleeve with buckle closure protects up to a 15-inch laptop. A zippered microfleece-lined top pocket holds an audio device or sunglasses, a stash sleeve stuffs a shell, and dual stretch-woven pockets carry water bottles. Shoulder straps are made with airflow mesh to keep you cooler in the heat. For day hikes, leave the laptop at home and slip a hydration reservoir in the computer sleeve, which comes with a tube port. A lanyard secures your keys, and an internal organiser holds pens and other small items. Made of a tough but supple 420-denier 100% nylon oxford plain weave with 840-denier 100% ballistics nylon reinforcements. The lining is 200-denier 100% polyester. Both are treated with a Deluge® DWR (durable water repellent) finish.
