Apeks WTX D40 Wing – Single Cylinder
Single-cylinder wings, often referred to as donut wings, are oval-shaped air cells or bladders that are not permanently attached to a harness. While single-cylinder wings have their origins in the realm of technical diving, they are becoming very popular in the recreational community. Not only are these single-cylinder wings streamlined, but due to their shape being a continuous loop, they are very stable underwater. There is no dramatic shift of air from left to right.
Apeks single-cylinder wings are a smart design that allows a cylinder to nest deep inside them. These wings mate up nicely to the rest of the Apeks WTX collection of high-quality harnesses, plates and accessories. They can be configured in multiple ways to match your type of diving. As with the rest of the WTX collection, these single-cylinder wings are built from the finest quality materials. They are designed by Apeks and built in our own factory.
The WTX and WTX-D Series is a selection of harnesses, buoyancy cells and accessories which offer unparalleled versatility due to the modular nature of the whole system. Each component can be configured into a highly technical rig for those trained to push the limits or scaled down to make a travel-friendly set up suitable for any diver.
(WTX single tank adapter is not required)
