An easy-to-access sling backpack is up for your next challenge, whether running mountain trails or biking city streets. The teardrop shape is supportive and easy to swing around to reach the main zip compartment, so you don't have to slow down every time you need to check your phone. Interior mesh and stretch-woven pockets organize odds and ends like first-aid kits and energy bars, while another zip pocket at the shoulder is lined to protect valuables. For all-day comfort, the shoulder strap and back panel are padded with 3D spacer mesh that wicks moisture, dries quickly and enhances breathability. Style Name: Patagonia Atom 8L Sling Backpack.
