Welded rather than sewn seams are the

only way make 100% waterproof backpacks.

We WELD the seams of a highly polyurethane

coated nylon fabric to form liners. These  liners

are then sewn into our packs using the welded 

tabs. By using a liner on the inside, we can

give you more cycling specific features for your 

pack on the outside, like blinker mounts, pockets,

pocket attachment points, compression straps and

u-lock holsters. These liners also contain large

welded velcro panels to attach padded accessory

pouches to protect and secure your digital world.
