Built with forward momentum in mind, the Mass Sling combines the support of a backpack with the convenience of a courier bag. The sling design positions the Mass’s load right behind your shoulders, preserving your arm and torso mobility. A simple spin of the single strap provides access to all your gear. Sized to hold today’s mobile electronics, the main compartment opens with a side zipper to expose three pockets inside, including a padded one for a phone. A padded sleeve protects most 13-inch laptops or tablets. For carrying comfort, a molded back panel sheds moisture and allows a cooling airflow, and breathable, 3-D spacer mesh pads the shoulder straps to keep you cool. Exterior features include a reflective panel and lash point for attaching a light. Made of 8.4-oz 600-denier 100% recycled polyester with a slick 3.3-oz 200-denier polyester lining. Both have a polyurethane coating.

      Water resistant, yes, but not waterproof. The fabrics have a polyurethane coating and DWR (durable water repellent) finish.
