The Arbor Market 15L Daypack by Patagonia is ideal for individuals who prefer to tote their daily essentials on their back opposed to unevenly across the shoulder. With a 15L volume, this pack comfortably holds your laptop or tablet, a lunch and water bottle, souvenirs while traveling, and other small essentials. A single external pocket holds your cellphone and cash for quick purchases at the farmer's market or snapping photos while sight seeing, while the padded laptop sleeve safely holds your devices. Human Curve padded shoulders ergonomically fit around your upper body for all-day comfort whether you are out exploring a new city or for 12-hour days out of the house.
