I put my shoulder bag through punishing abuse every day, so I was excited to try the Urban Waterproof Shoulder Bag from SealLine. This large bag is constructed of burly, waterproof, 600-denier, urethane-coated polyester that sheds water like a duck’s back, keeping everything inside well-protected from the elements. Convenient features like an external zip pocket, internal organizer/divider, and corner pockets add commuter-smart organization, and the simple, yet effective Quick-Clip closures allow for one-handed access to all my stuff. If you need more storage, the bag is compatible with SealLine’s innovative Modular Accessory Pocket (M.A.P.) system that attaches additional zip pockets or mobile electronic cases. Other notable features include a carry handle, bike-friendly hideaway waist belt, a light clip-loop, and a padded shoulder strap and back panel to make a heavily loaded bag much more comfortable. Top it all off with cool color options and clean styling and this bag certainly gets my seal of approval. $190; cascadedesigns.com.
