Thinsulates & Undersuits

SORT BY: Product Price Default
Ursuit X-TEX Finnfill Undersuits
Ursuit and Finnfill technology bring you warmth without the stiffness or bulk.

Finfill material does not lose its insulation capacity even after many washes as opposed to thinsulate and regular wadding. Even better, it actually gains thermal properties if dry cleaned. Ursuit's X-Tex range of Finnfill undersuits are the ideal choice for active divers throughout the world.

X-Tex Finnfill undersuits are exceptionally flexible and watertight,  providing perfect thermal insulation ranging from 0.83 CLO in the 'Light' version to 1.97 CLO for the all-season 'Heavy' style.

Four layer structure: 
Each Ursuit Finfill undersuit is manufactured from 4 layers with the special Finnfill fibre as an insulating layer a and breathable watertight X-Tex membrane as the intermediate layer. The surface of these suits are made of elasticated and slippery tricot fabric and the inner lining has the comfort of fleece.

4th Element SUB-30 Technical Garmet Wash
We have been asked so many times what the best product is for washing fourth element thermals. Over the 4th Element tried many different washing detergents: some had built in softeners, others had optical whiteners and others were just too damaging to the environment. Finally, they decided to work on our own specially formulated detergent for washing technical sportswear at low temperatures.

DirDirect is a world-leading online dive shop run by Underwater Explorers based in Portland, Dorset, UK. Underwater Explorers is a dive centre with a striking difference. It was born out of the concept of "Hogarthian" diving, safe and streamlined equipment configuration, using the most robust products available for recreational and technical diving -- but at the same time, keeping it simple. It is based on the concept of "less is more" in diving and acts as an equipment outlet, training facility and source of sound advice.

Thank you for the excellent service and reasonable prices! I will highly recommend your store to my friends.
