SF TECH TNT ONE drysuit

SF TECH TNT ONE drysuit

The TNT One SF Tech drysuit redefines the approach to technical dry diving. It combines the lightness and quick drying of a trilaminate construction with the thermal properties of high-density neoprene, offering a rare balance between insulation and mobility.

The Yamamoto high-density neoprene trilaminate provides a significantly better thermal feel than a conventional butyl trilaminate, while maintaining great freedom of movement. It is the first trilaminate to incorporate 4-way stretch elasticity, limiting the stiffness often found in traditional drysuits.

Featuring a telescopic torso and front zip, the TNT One allows divers to suit up independently, which is essential for technical and demanding diving.

The suit offers enhanced protection thanks to a blend of aramid fibres (DuPont™ Kevlar®) and high-performance polyethylene (uhmwpe) in high-risk areas such as the knees, sides and waistband.

A waterproof suit that accompanies you on all your underwater adventures, for controlled air volume management without excessive buoyancy and increased stability when kicking and in horizontal trim.

*The total weight of the suit is around 4 kg, depending on the configuration and options chosen.

❓ Frequently asked questions (FAQ)

Why is there no size chart for this model ? The SF TECH TNT ONE is exclusively made to measure. This ensures that every movement is fluid and that no unnecessary air pockets interfere with your buoyancy or thermal comfort.

How should I care for TNT material ? As with any high-end equipment, rinsing with fresh water after each dive is sufficient. The use of a suitable lubricant for the metal zip is recommended to maintain its fluidity and longevity.

Is it suitable for diving in very cold water ? Absolutely. Its titanium and high-density neoprene design makes it one of the most effective wetsuits for icy waters, while remaining comfortable in temperate waters thanks to its breathability and flexibility.
