50L Roll Top Waterproof Motorcycle Luggage Bag

Sealock is a professional manufacturer and OEM supplier of the 50L Roll Top Waterproof Motorcycle Luggage Bag (model SL-C619), built for riders who need dependable dry storage through heavy rain, dusty trails and long touring days. At Sealock, we have welded waterproof gear since 2003, and this 35L/50L motorcycle dry bag is the result of that experience: a 500D PVC tarpaulin body where every seam is joined by high-frequency welding instead of stitching, so there are no needle holes for water to creep through. The roll-top design lets a rider close down a half-empty bag or expand it for a full kit, while POM buckles and high-strength nylon webbing lash it firmly to a rear rack.

The welded anchor layout is designed to strap quickly onto most rear racks, so the same tail bag works across very different bikes:

• ADV motorcycles
• Touring motorcycles
• Dual-sport motorcycles
• Enduro motorcycles

Because it lashes down rather than bolting on, riders can move the bag between bikes or pull it off as a grab-and-go dry sack at the end of a ride.

Every order runs through the same line we have refined over two decades. The PVC tarpaulin is cut, the reinforcement panels and D-ring patches are welded onto the high-stress areas first, then the main body seams are welded and the roll-top and webbing are fitted last. Before a batch ships, units are pulled for a water-jet test that reflects the IPX6 rating, the buckles and webbing get a pull test, and the welded anchors are loaded to confirm they hold under strap tension. We would rather catch a soft weld on our floor than have a customer find it on a wet motorway.

As the factory, we support OEM and ODM on the 50L Roll Top Waterproof Motorcycle Luggage Bag : custom colours, your printed or welded logo, sizing tweaks and adjusted anchor layouts for a specific rack platform. Sampling runs 7–15 days, bulk production is 30–45 days, and our monthly capacity reaches around 30,000 units, so we can cover both first orders and recurring wholesale programs. If you sell into the ADV and touring market and want a welded tail bag under your own brand, we can quote against your spec directly.

We back every shipment with pre-delivery QC inspection and replacement for any genuine welding or material defect found on arrival. Orders are documented from sampling through final inspection, and our team stays reachable for spec questions, re-orders and packaging requirements after the sale.
