The Patagonia Yerba 22L Pack is a single compartment daypack with self-fabric back panel, Airflow-mesh shoulder straps for comfort and breathability, and an exterior stuff pocket. This cleanly designed backpack has the room and features to hold a day's worth of goods when you hit the trail, bike path or subway. Inside, a raised, padded sleeve with 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.
