The Patagonia Atom Sling Pack takes crowded streets, dusty trails and muggy subways in stride. Equal parts courier bag, backpack and carry-all, this sling bag's teardrop shape provides the support of a backpack with a single-strap design that makes it simple to access your things just spin it around to your chest. The large zippered main pocket has mesh and stretch-woven pockets inside (also zippered) to organize small items. A convenient zippered pocket on the shoulder strap has a soft lining to protect valuables; adjustable buckles lash any extras to the outside. Breathable 3-D spacer mesh pads the shoulder strap and back panel to wick moisture, dry quickly and increase ventilation. For biking and hiking, an integrated waist-belt keeps the pack close to your torso.
