Our History . . .

Although we are predominately known for our vast range of divewear and diving equipment, designing and producing world-class wetsuits is steeped in our 45-year history.

The previous design of our Marlin Triathlon wetsuit was worn by top triathletes such as Faris Al Sultan (2005 Ford Ironman Kona World Champion), and Christof Wandratsch, who set the (then) world record for the fastest ever swim of the English Channel in 2005.

We are proud to have produced such high-calibre apparel, and you can expect even more from our new Triathlon suit and range of essentials.

Drawing from our wealth of experience and past success’, we have developed our kit even further, so you can be sure you are buying the best quality kit you need to maximise your pleasure and performance in the water.


100% customer service with your open water wetsuits and wildwater swi equipment
