Sized for action, this cleanly designed daypack has the room and features to hold a day's worth of essentials when you hit the trail, bike path or subway. Its single compartment accommodates reading materials, lunch and a jacket; inside, a raised, padded sleeve with a buckle closure holds most 15-inch laptops. A zippered, brushed tricot-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 Air Flow 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 internal dump pockets organize your 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. All are treated with a Deluge DWR (durable water repellent) finish.
