The Commuter-Bag combines an urban design with waterproof functionality. A buckled flap allows quick access to the main compartment while the internal organizer can stow 8-10" tablets. (Laptop is stored in separate sleeve). An outer pocket (not waterproof) keeps small items such as smartphone, keys, etc. within reach. The QL3 mounting system also provides simple mounting with an uncluttered back of the bag since the hardware stays on the rack.
