The WTX and WTX-D Series are a selection of harnesses, buoyancy cells, and accessories that 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 setup suitable for any diver. Designed for public safety divers but suitable for all other styles of diving, these 30-lb. 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 a reduced risk of bacterial growth due to the slick surface.
