The Katana 2 harness sets a new standard in sidemount diving. Designed in collaboration with Edd Sorenson from Cave Adventurers, Hollis developed a unique new 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. Hollis 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.

QFS Quick Fit System offers fine tuning of the torso height between small and large divers for a true one-size-fits-all. Depending on user preference, design allows for an H" or Y" style harness configuration. Lift capacity is 40 lbs. (18.14 kg) with an innovative wing design to keep the diver profile even lower than the competition and without the turtle shell effect, which causes drag. Standard weight capacity 20 lbs. (9.1 kg), to offset added buoyancy in cold water with dry suits and thick undergarments. Two optional 5 lbs. (2.26 kg) weight trim pockets available.

Easy to reach attachment points for accessories on the side of the wing. Innovative top dump allows venting of gas without breaking trim or reaching behind the wing like in other designs. Integrated sidemount CCR mount. The dual bladder option is ideal for technical dives in a wetsuit. 

Reversible Inflators & Dump assemblies. Primary bungees integrated into to wing to pull tanks upward away from diver's torso and integrated retainers located to avoid overhead interference. Harness comes with multiple shoulder, waist, and crotch strap stainless steel D-rings for rigging and accessory attachment. The harness is made from durable webbing and has a stainless-steel latch-style waist strap buckle. The Katana 2 has a 1000-Denier Cordura nylon, polyurethane lamination outer shell, and dual 15mm urethane radio frequency (RF) welded seam internal bladders. Dual Hollis Gear Power Inflator Mechanisms are made from durable impact-resistant plastic with internal components and inlet quick-disconnect nipples made from chrome-plated brass.
