Equal parts courier bag, daypack and carry-all, this sling bags teardrop shape provides the support of a daypack by positioning the load behind your shoulder. The single-strap design makes getting to the goods simple: Just spin it around front. 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, a stow-away waistbelt keeps the pack close to your torso. Made of a 420-denier 100% nylon oxford plain weave, with an 840-denier 100% ballistics nylon bottom. The lining is 200-denier 100% polyester. All fabrics have a Deluge DWR (durable water repellent) finish.
