Excellent for sport and technical divers, this drysuit has set the industry standard for meeting drysuit diver expectations. Durable, quick-drying and lightweight for travel, the TLS350 is so versatile it's become the top choice of underwater photographers, deep cave explorers and US Navy 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 lightest drysuit, the TLS350, is constructed with high quality tri-laminate materials that were originally developed to meet the demands of chemical warfare. In the 1980s, the US military made a request for a suit made of the lightest material available, which would require little maintenance and be easily repaired if necessary. At that time, combat swimmers' suits were typically of the vulcanized rubber type, which, although tough, constrained swimming motions. As the military searched for a more suitable alternative, an actual swim test was needed to quantitatively compare the vulcanized rubber suit to newer designs. The test required swimmers to put on their respective wetsuits and swim a measured distance in a given time. The TLS350 performed very well when it came to donning and swimming. Interestingly, the features that made this garment desirable for military divers and search and rescue teams made it equally desirable for civilian divers. The telescoping torso design of the TLS results in a suit that is both streamlined and easy to don. It allows for enough material for a full range of motion without promoting drag. Because fabric suits do not stretch as much as neoprene suits, if there was not enough material available, the diver's range of motion would be limited. Also, to ensure longevity while maintaining a full range of motion, the number of seams should be kept to a minimum. This requires a careful balance. By using a bespoke production suit or an appropriate standard size suit, a proper fit can be achieved, allowing the diver to have the most streamlined suit possible while incorporating sufficient thermal protection.
