Get a delivery across town or just pedal your bike to work with the Patagonia Critical Mass Bag. This large messenger bag features a 100 recycled polyester outer and makes it easy to carry all your gear on your commute. A large reflective strip adds visibility when youre riding in low light, and Patagonia padded the back panel and added a padded sleeve for your laptop up to 17-inch. Keep you MP3 player, phone and keys in the exterior pockets for easy access while riding. A padded shoulder strap and a webbing waist belt keep the bag close to your body when youre dodging through traffic.
