Originally created for public safety divers, this modular wing system is equally at home in technical, recreational, or travel diving setups. Featuring a tough Armoguard slick skin exterior, these 30 lb and 40 lb donut-style wings resist abrasions, dry faster, and inhibit bacterial growth—perfect for demanding conditions. With a rapid exhaust dump valve, heavy-duty YKK zip, and the ability to integrate seamlessly with WTX or webbed harnesses, the WTX-D PSD system provides versatile performance, whether you’re pushing limits or keeping it compact.
