Carrying a light load? Leave your BOB stroller at home and put your stuff in the spacious 2100-cubic-inch BOB messenger bag. Built of the same waterproof, PVC-coated, nylon fabric as the BOB Dry Sak, it keeps all your essentials dry, day after rainy day. Its padded internal divider, ergonomically attuned shoulder strap, large zippered pockets, and load-stabilizing waist strap ensure your cargo is carried comfortable and securely. Bright yellow for visibility.
