Hollis Custom Katana 2 Dual Wing Aqua

Minimalist Sidemount System for Technical Diving
Designed for dedicated sidemount divers, this dual wing sidemount system supports a wide range of diving configurations including warm water, cold water, wetsuit, drysuit, open circuit, and sidemount CCR applications. The low profile modular design minimizes drag while maintaining stable buoyancy control for both steel and aluminum cylinders. Its streamlined wing structure reduces the "turtle shell effect," helping divers maintain improved trim and movement underwater.

Dual Bladder Wing with Adjustable Fit System
The integrated QFS (Quick Fit System) allows fine tuning of torso height for both smaller and larger divers, creating a versatile one size fits all configuration. The dual bladder wing delivers 40 lbs (18 kg) of lift while maintaining a compact underwater profile. A standard weight capacity of 20 lbs (9 kg) helps offset added buoyancy when diving in cold water with drysuits and thick undergarments. Designed specifically for technical diving, the dual bladder sidemount wing incorporates a second redundant power inflator routed from the right side for added redundancy and control.

Customizable Harness and Advanced Utility Features
This technical sidemount wing supports both "H" and "Y" style harness configurations, allowing divers to customize setup preferences based on diving style and equipment routing. Easy to reach accessory attachment points improve equipment organization, while the innovative top dump valve allows gas venting without breaking trim or reaching behind the diver. An integrated sidemount CCR mount expands compatibility for advanced technical diving systems, and hard coated stainless steel hardware with Black PVD treatment increases durability in demanding underwater environments.
