Representing the latest incarnation of Mission Workshop‘s Transit Series shoulder bags, the Mission Workshop Helmsman is waterproof and unbreakable, constructed from HT500 outer fabric with a urethane-coated nylon ripstop liner. The rolltop duffle easily attaches to the front of any bike, packing four quick-access cargo pockets and two zippered pockets on the outside, while the roomy main compartment has a separate zippered padded laptop sleeve. Multiple carry options include hide-away grab handles and a removable quick-adjust shoulder strap, as well as an optional backpack harness that can be ordered separately.
