TiZip
Also: TiZip Superseal, gas-tight zipper
TiZip is a manufacturer of air- and watertight zippers. In packrafts they turn the tube into a luggage compartment.
MRS describes the TiZip as a high-quality mechanical seal bonded into the hull. The care formula is: BRUSH · DRY · AIR OUT · LUBRICATE with TiZip silicone grease. Rinse or brush off sand before opening. A small toothbrush helps. Alpacka calls the system Cargo Fly.
