Product Information
This bicycle courier backpack carries the heavy, the awkwardly shaped and the diverse. With a slight trapezoidal shape and a streamlined design, it keeps the loads of a bike commute close to your back to preserve your dynamic mobility. The main compartment accommodates lunch, books and extra clothes. A padded sleeve, raised above the bottom of the backpack, holds and protects a 17-inch laptop. Interior pockets include a drop-in for a wallet and gym pass, a mesh pocket to hold your keys, a padded electronics pocket for your phone and three slots for pens. Two exterior mesh pockets hold water bottles, and lash points secure a U-lock and/or bike light. The reflective panel in the middle of the pack keeps you visible for dawn and dusk treks. Other features include a molded back panel to keep you cool, shoulder straps with mesh padding to move moisture and a waistband to secure the load. 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.
