The Wrist Pouch is designed to fit comfortably around your gauge, up to 1.5 inches wide (4.25cm). This provides excellent accessibility in a whole range of potential situations. It is also ideal as a pouch option for those who anticipate much usage or for those on working projects. Please note that this is designed to be worn over neoprene, dry suits, and other garments. The pouch is not designed to be worn against the skin. The pouch can also be worn on any 1.5 inch wide utility belt. The pouch fits neatly against the wrist, and does not extrude.
