Hollis SMS Katana 2 Multicam Limited Edition
The Katana 2 harness sets a new standard in sidemount diving. Collaborating with Edd Sorenson from Cave Adventurers, we developed a unique “Quick Fit System” enabling users to easily customise the one-size-fits-all harness to their specific size or preference in minutes. This includes increased lift and weight capacity, single and dual bladder options and the highest quality materials Hollis is renowned for.
Furthermore, Katana 2 is the world’s first sidemount harness designed with closed circuit sidemount capability, featuring integrated mounts for the popular KISS sidewinder. It truly breaks away from traditional designs, offering greater customisation and versatility.
