The first batch is sold out but we have a second run coming that will be shipping on December 20th. Pre-order now to take advantage of the 20/20 Black Friday sale.The Mass Transit is now available in Ultra for a limited production run. Our largest duffle offers twenty-five percent more capacity than the standard Transit. Designed for travel, it delivers a balance of minimal weight and high durability, made with Challenge Sailcloth Ultra 200X, a high-performance laminate that combines UHMWPE (Ultra High Molecular Weight Polyethylene) with recycled polyester film. The result is a fabric with an outstanding strength-to-weight ratio, excellent abrasion resistance, and reliable water resistance.On the exterior, the bag includes YKK Aquaguard matte-finish zippers, a spacious laptop compartment, two zip pockets for pens, cords, and chargers, and four open compartments for magazines, books, and water bottles. Inside, it provides 33.6 liters (2,050 cubic inches) of storage along with four side dividers for organization.The Mass Transit can be carried using grab handles that tuck away when not in use or with a removable quick-adjust shoulder strap that features our custom aluminum hardware. The duffle also attaches to any porteur-style back rack using the integrated snap points. For hands-free travel, it can be worn as a backpack when paired with the optional harness.
