xDeep Hydros Wing 40lb

from* $459.00
The donut wing design greatly reduces the movement required to redistribute gas around the wing, particularly for operating the hip dump valve. This 18kg | 40lb version is ideal for twin 12L | 100cf steel or twin AL80 cylinders.
Manufacturer: xDeep
Wing shape and design

The 360 degree donut air bladder allows air movement in all directions. This is a big advantage over traditional horseshoe bladders which require breaking trim to raise the top edge and move air from the right side to the dump valve on the left. 

HYDROS wing has been designed and built in such a way that its centre of buoyancy is placed on exactly the same level as the gravity centre of gas in the cylinder.  Accordingly, the trim does not change during the entire dive and remains the same with full and empty cylinders.

The geometry of HYDROS, especially the contour of the wing, provides significant righting moment, which makes it a lot easier to reach and maintain the correct horizontal position.

To make access to the valves easier, xDeep have massively reduced the dead zone in the upper part of the bladder to a minimum. As a result, there is no "loose cloth" effect that otherwise makes access to valves difficult while doing a V-Drill (or in an actual emergency shutdown).

The reduced bladder volume just below the first stage regulators also makes guiding hoses much easier and the inflator head does not need to be lifted as high as other designs in order to release air.

In the HYDROS, xDeep reduced the part of the wing that sticks out above the water while the diver is surfaced.  Therefore, a significant part of the wing’s displacement is used to keep the diver surfaced, rather than having a larger ineffective area positioned above the waterline.  You can feel the difference when surfaced in high wave conditions, especially if you have full stage cylinders.


The outer cover is made from Cordura 1100 dTEX with waterproof thermo welded polyurethane coating for high damage resistance. 

Moisture inside the wing is an ideal place for bacteria to grow, including the pathogenic ones. In order to reduce that risk, the inner bladder of HYDROS wing contains antibiotic agent minimising the development of bacteria.

Constructed using highly precise and durable manufacturing techniques: ultrasonic welding, laser cut fabric, and high frequency welding. 

Triple fully trimmed seams using Amann Serabond thread (specialist marine environment thread from Germany).


"K" type power inflator is a balanced piston type inflator, which enables precision in adding as to the wing. The body of the inflator is high durability poliacetal. The valve seat is metal and therefore more resistant to freezing than full plastic inflators.
