Waterproof Bicycle Bags with High Frequency Welded Seams

TPU laminated nylon welded rather than sewn, so there are no needle holes.

What This Category Is For

These four bags are built on a different principle from the sewn range. Nylon in 420D to 840D is laminated to a TPU waterproof membrane, a PP board keeps the shape, and the seams are high-frequency welded rather than stitched. The waterproof triangle bag goes further and uses three different fabric weights, putting 840D on the bottom where wear happens.

The Problem It Solves

A sewn seam has a needle hole every few millimetres. Coating the fabric does not fix that. Welding fuses the panels together, which is the only way a fabric bag is actually waterproof.

  • Bikepackers and tourers
  • All-weather commuters
  • Brands that want to make a real waterproof claim
FAQ

Waterproof Bag Questions

What does high frequency welding do?
It fuses the TPU-coated panels together with no stitching, so there are no needle holes for water to track through.
Why does the triangle bag use three fabrics?
840D on the bottom for wear and spray, 600D outside for abrasion, 420D inside where nothing rubs. It saves weight without giving up durability.
Are the zips waterproof too?
Yes, the welded bags use waterproof one-way zips.
Which is the most hard-wearing?
The tail bag uses 840D throughout, because it sits directly in the rear wheel spray.
