Marscamd Waterproof Motorcycle Tail Bag, 64L Expandable Black — Rack‑Mount, Rigid‑Bottom & Rain Cover

Marscamd's Waterproof Motorcycle Tail Luggage Bag is a 48–64L expandable, water-resistant tail pack designed to secure gear on rear racks while staying weatherproof and easy to carry.

Built to handle daily commuting, weekend rides and longer touring trips, this black Marscamd tail bag combines a rigid-bottom main compartment, an expansion zipper, and a supplied rain cover so your kit stays dry and organized. Reflective strips and multiple carrying options make the bag practical both on and off the bike, while exterior webbing and elastic cords give you attachment points for extra cargo.

How does the expandable capacity work for different trip lengths?

The bag stores at its compact 48L footprint for shorter rides and unzips to expand to 64L when you need room for an extra helmet, jacket, or camping gear. The expansion uses a full-perimeter zipper so the shape remains stable when loaded.

• Normal size: 19.5" x 14" x 13.5" (48L)
• Expanded size: 25" x 14" x 13.5" (64L)
• Full-perimeter expansion zipper for predictable shape
• Bottom panels to prevent sagging under load

Will this bag protect my gear from rain and road grit?

The outer fabric is water-resistant and the bag includes a dedicated rain cover to guard against heavy downpours and road spray. Sealed seams and the supplied cover help keep dust and moisture away from electronics, clothing, and other packed items.

• Water-resistant fabric construction
• Included rain cover for heavy weather protection
• Reflective strips increase visibility in wet conditions
• Interior straps hold items steady to reduce movement and rubbing

How does it attach to the bike and stay secure at speed?

Installation uses four end-mounted straps that loop over the rear rack and fasten with quick-release buckles, allowing the bag to be removed quickly without detaching the mounting straps. Exterior webbing and buckle straps let you cinch top loads and add modular pouches for extra security.

• Four mounting straps with quick-release buckles
• Exterior elastic cord and buckle straps to secure top items
• Webbing for attaching tactical pouches or tie-downs
• Reflective strips help with night visibility when traveling

What carrying options and organization features are included?

The bag offers multiple carrying choices—two strong top handles, a detachable shoulder strap, side handles and a back luggage strap that slides over rolling suitcases. Inside, elastic tie-down straps and side pockets keep shoes and small items separated and ventilated.

• Top handles, side handles and detachable shoulder strap for versatile carry
• Back luggage strap for stacking on larger suitcases
• Side ventilated shoe pocket and small-item pockets
• Interior elastic tie-down straps to reduce shifting

Who is this for? The Marscamd Waterproof Tail Luggage Bag suits riders who need a reliable, weather-resistant rear pack that adapts from day trips to extended rides. It fits motorcyclists who value secure mounting, quick removal, and organized storage—commuters, weekend tourers and any rider who wants extra cargo capacity without a permanent hard case.
