The SF Tech TNT is made of a revolutionary Patent-Pending material: a high density neoprene based trilaminate, with two extra layers of Titanium acting as heat-reflective panel. The overall material feels up to 2x warmer than a standard butyl trilaminate.

The TNT offers all the advantages of trilaminate while being more flexible and warmer like a neoprene: The best of both worlds!

To guarantee strength and reliability, the overall suit is made of aramid fiber (DuPont™ Kevlar®) reinforced fabric. Only the best materials available on the market are used. The high-density neoprene is made by Yamamoto while the DuPont™ Kevlar® is made in Switzerland.

The SF Tech TNT is the perfect drysuit for demanding divers looking for a tailor made, top of the line drysuit with unprecedented freedom of movement and unequaled robustness.

As standard, the SF Tech TNT comes with a front entry zipper and telescopic torso allowing the diver to be self-sufficient in the donning and doffing process. The fold of the suit is held in place by a crotch strap.
