DUI TLS350 Drysuit - Made to Measure

Excellent for sport and performance divers, the DUI TLS350 Drysuit has set the industry standard for what divers have come to expect from a drysuit. It is durable, fast drying and lightweight for travel.

The TLS350 Drysuit is so versatile that it has become the primary choice for underwater photographers, deep cave explorers and the US Navy SEALs.

The TLS’ telescopic torso design yields a streamlined and self-donning suit. It allows enough material to be available for a full range of motion without at the same time promoting drag. Because fabric suits do not stretch as much as neoprene suits, the diver’s range of motion will be restricted if there is not enough material available. Also, to ensure longevity while maintaining a full range of motion, the number of seams must be kept to a minimum.

History of the DUI TLS350

The DUI TLS350 drysuit is constructed with high-quality trilaminate materials that were initially developed to meet chemical warfare requirements. In the 1980's the US military requested a suit made of the lightest material available, which would demand little maintenance and be easily mended or patched if necessary.

At this time, combat swimmer suits were typically of the vulcanised rubber type, which, although tough, exhibited poor swimming characteristics.

While the military searched for a more suitable alternative, an actual swim test was needed to compare the vulcanised rubber suit to new designs quantitatively.

The test required swimmers to don their respective suits and swim a measured distance in a specified time. The TLS350 faired very well with respect to self-donning and “swimmability.” Interestingly enough, the features that made this suit desirable to military divers and search and rescue teams made it desirable to cave divers.
