Designed for Public Safety divers (PSD) but a very practical and attractive option for all styles of diving, these 30 and 40 lb single cylinder wings boast all of the same features as the 30 and 40 lb single tank wings but are constructed from an Armoguard slick skin. This fast drying material is more abrasion resistant than traditional Cordura® and due to its slick nature it rinses easily and even if it is stored while damp it doesn’t pick up bacterial growth or odours.
