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. Designed for public safety divers but suitable for all other styles of diving, these 30 and 40 lb single cylinder donut wings boast all of the same features as the WTX-D30 and WTX-D40, but are constructed from super-tough Armoguard slick skin for increased abrasion resistance, faster drying and have a reduced risk of bacterial growth due to the slick surface.
