Patagonia Critical Mass Bag

Built for the two-wheeled commute, the Patagonia Critical Mass Bag is a large messenger bag designed to carry it all. The Critical Mass's main compartment is padded on the back and along the contoured base to provide protection and structure for the stay-open design. Inside, a removable, padded computer sleeve suspends a 17-inch or smaller laptop off the ground and has a file organizer built into its side. The cover flap extends over the sides of the bag to protect contents from rain and a low-profile front pocket closes with a water-resistant zipper. External side pockets hold a cell phone, keys and power brick. Other features include a padded, adjustable shoulder strap with a self-closing buckle, a removable shoulder strap pocket for easy access to an MP3 player or cell phone, a stowable waist strap, bottom compression straps that hold a yoga mat, and a reflective strip for better visibility in low light. Made with a 600-denier recycled polyester exterior and a 200-denier polyester liner; both have a polyurethane coating and a DWR (durable water repellent) finish.
