Diving Unlimited International, Inc. is the world’s leader in designing and manufacturing drysuits to the highest quality standards. 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.
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.
The FLX Extreme Premium drysuit is perhaps the most popular choice among advanced technical divers and exploration divers due to its flexibility and durability. It features a heavy polyester trilaminate that is thicker than the TLS350, with added Cordura® overlays on the legs for increased protection and durability.
The CLX450 Classic Premium drysuit is a world-class suit developed for overhead environments, featuring lightweight materials tough enough to crawl through narrow restrictions, yet that dries very fast, making it perfect for travel and extremely cold climates. The upper body is made of a heavy-duty CORDURA® trilaminate, offering a superior ballistic abrasion resistance, while the lower body is made with a more flexible Polyester trilaminate.
The CF200X Premium drysuit is perhaps the toughest and most durable drysuit, and a high-demand choice of technical and professional divers around the world. It is made entirely of 1mm crushed neoprene (starting off as 3mm), which is highly dense, abrasion and puncture resistance, yet still highly flexible and stretchable, making it the most durable substance used in the construction of drysuits today.

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.
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.
