Quite possibly the best sidemount wing presently on the market.
 
The Katana 2 harness sets a standard in sidemount diving. Designed in collaboration with Edd Sorenson from Cave Adventurers, Hollis developed a unique “Quick Fit System” which allows users to easily tailor the one-size-fits-all harness to their specific size or adjustment preference in a matter of minutes. They added more lift, more weight capacity, single and dual bladder options and the best quality materials Hollis has always been known for.
 
Katana 2 is also the first sidemount harness in the world to be designed with closed circuit sidemount capability, with integrated mounts for the popular KISS sidewinder. Katana 2 breaks away from traditional designs and offers more customization and versatility.
