HYDROS 40 model is definitely more narrow than various 40lbs wings from other manufacturers. The Small width makes it ideal for 2x7 twinset where other wider wings fail to perform well.

Thanks to smaller width, the side parts of the wing do not stick out above the cylinder – so the inflator works considerably better.

HYDROS 40 model is also good for 2x12 twinset for ambitious recreational dives.

Better Trim and Greater Stability

HYDROS 40 model was 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. Thanks to this, the trim does not change during the entire dive and remains the same with full and empty cylinders.

Easy Access To Valves

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

To make access to the valves easier, we massively reduced the dead zone in the upper part of the bladder to the minimum. As a result, there is no "loose cloth" effect which makes access to valves difficult while doing a V-Drill.

The reduced bladder volume in the place where hoses are situated makes guiding them also much easier.

High Surface Position

In the HYDROS 40, we reduced to minimum the part which sticks out above the water while the diver is surfaced. Therefore, the significant part of the displacement is used effectively to keep the diver surfaced.

You will feel the difference during high wave dives at sea, especially when you have with you full stage cylinders.

Super Resistant Cordura

The outer shell of the HYDROS model is made of highly durable Cordura® 1100 dTEX produced in Germany.

For safety reasons, no one needs to be convinced that you need a very durable outer shell for wreck diving.

Also, remember that the Cordura® fabric is definitely more abrasion-resistant than other materials. Compared to other wings made of less expensive materials, the HYDROS model stays NEW for a longer period of time.

Choose the Inflator with Optimal Length

The comfort related to the use of inflator depends on its length. An inflator which is too long or too short may even cause the best wing or jacket to be uncomfortable to use.

Depending on your height, you need an inflator of greater or smaller length. When you order HYDROS wing, you can choose from three different lengths of the inflator hose: 14", 16" or 19". You are sure that your set will ideally match your needs.

Anti-bacterial Coating

Have you ever wondered why scuba divers have so much sinus trouble?

Moisture inside the wing is an ideal place for bacteria, including the pathogenic ones. You know perfectly that sinus trouble can force you to refrain from diving for many weeks.

In order to reduce that risk, the inner bladder of HYDROS wing contains antibiotic agent preventing the development of bacteria.
