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.
