The Zeagle Stiletto is a rugged, full featured but light weight BC designed for the diver who may do both warm and temperate water diving and don't need the twin tank capability or higher lift of Zeagle's heavy-duty BC's. The Stiletto's extra durable reinforced 1000 denier nylon bladder material, gives an extra level of protection against abrasion or punctures in close environments like the edge of a coral reef or wreck. It has sufficient lift and weight capacity for most average sized divers to use in their local environments, yet packs easily into a lightweight travel system. | Zeagle Octo-Z Alternate Air Source The high performance design of the Octo-Zs regulator section provides easy comfortable breathing at all Sports-Diving depths.
