From humble beginnings in 1963, today, DUI has a stellar reputation for their high-quality, durable suits, made for abuse, and designed for functionality and warmth, and is widely considered the gold standard in drysuit manufacturing. DUI suits are used worldwide in every environment and condition imaginable, and by every level of diver.

TLS 350

The TLS350 Premium drysuit is so versatile, it has become the primary choice for underwater photographers, deep cave explorers, and US special operations swimmers, divers, and rescue professionals. The TLS350, is constructed with high-quality trilaminate, includes a telescopic torso, is fast-drying, light-weight, and can be used from the warm waters of Florida to the ice-covered seas of Antarctica alike.

DUI Drysuit Insulation (Undersuits)

Thermal garments/undersuits are used to keep you warm when diving in a drysuit. For most drysuit dives, you will be wearing some level of thermal protection. Thermal undersuits are available in a wide range of styles, thickness grades, and materials, and are best used in layers. A moisture-wicking "base layer" should always be worn against the skin, with additional layers used as appropriate for the environmental conditions and type of drysuit worn.

DuoTherm II 150 Jumpsuit (Unisex)

The DuoTherm II Jumpsuit 150 is made from a Heavy Stretch Fleece (280 gm/m2), is pill-resistant, stretchable, and is an excellent option for warmer water diving [16°C and up (60°F and up)], or can be used as a base layer for extremely cold dives when layered with a base layer underneath and a 300 layer over top.
