Click into your pedals and spin down the soaking wet bike path with the Seal Line Urban Backpack carrying your laptop and a change of clothes. This waterproof backpack uses river-bag technology to ensure your cargo stays dry through a torrential downpour. PVC-free double-coated fabric provides plenty of durability to handle the daily grind, and SealLine added a comfortable molded back panel to manage heavy or awkwardly sized loads.
