Excellent for sport and performance divers, this drysuit has set the industry standard for what divers have come to expect from a drysuit. Durable, fast drying and lightweight for travel. The TLS350 is so versatile that it has become the primary choice for underwater photographers, deep cave explorers and the US Navy SEALs. By varying the insulation underneath, you can use the TLS in the warm waters of Florida to the ice-covered seas of Antarctica.

Our most lightweight & fast drying drysuit available, the TLS350, is constructed with high-quality trilaminate materials that were initially developed to meet chemical warfare requirements. In the 1980's the US military issued a request for 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 vulcanized 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 quantitatively compare the vulcanized rubber suit to new designs. 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.

The TLS’ telescopic torso design yields a suit that is both streamlined and self-donning. 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, if there is not enough material available, the diver’s range of motion will be restricted. Also, to ensure longevity while still maintaining a full range of motion, the number of seams must be kept to a minimum. This requires a careful balancing act. Utilizing Special Production (i.e. Cave Cut) or appropriately sized stock suits, a proper fit can be achieved, allowing a diver to have the most streamlined and “swimmable” exposure protection possible while incorporating sound thermal protection.

About us

Company details

Skin Diving Unlimited started in 1963 because our founder, Dick Long, loved to dive. And at 6’2” and 130lbs, he was always freezing. He opened a dive shop in San Diego with $1500 and an old air compressor and started making custom wetsuits. Through his innovative designs and techniques, he quickly garnered a reputation as “The Guy” to help keep divers warm.

In the late 60’s, DUI invented hot water suits and systems for commercial and military divers. This allowed divers to go to deeper depths and for longer periods than ever believed possible. DUI’s designs were used in the frigid waters of the North Sea for the Offshore Oil Industry and in SeaLab I & II. And divers welcomed the Apollo astronauts back to earth wearing their custom designed DUI wetsuits.Our heart has always belonged to the recreational diver because we love diving, too. So we decided to use the expertise we developed with commercial and military divers to help recreational divers improve their underwater experience. How could we help sport divers dive more often and in more comfort? This began our current obsession with fit, quality materials, impeccable workmanship and new innovations.
