5MM Reactive Wetsuit

colour: {{selectedColorTitle}}

reacting to the human element

The suit is made with scientifically proven Celliant® Infrared Technology - 13 thermo-reactive minerals woven into the fabric lining that convert body heat into infrared energy and reflect it back onto the diver. Medical studies have shown that infrared energy improves the body’s circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improving overall warmth and increasing your dive time.


Medical trials show that infrared energy improves circulation and increases tissue oxygen. The result? Celliant Infrared Technology helps conserve lost body heat and accelerate thermal recovery. Keeping you diving longer and recovering faster.

Seamingly perfect

The first dive wetsuit made without a single seam stitch, Reactive uses our patented No Stitch Technology (NST). NST isolates the body from the water eliminating seam leakage using taped seams inside and out. Using the power of Celliant ® Infrared Technology to insulate the body, combined with NST, this creates the world’s warmest dive wetsuit.

Ridiculous Warmth

Spend an hour diving in my new suit… very comfortable down to 12c for that extended period of time. Only thing that stopped me from going deeper and colder were my gloves and hood… will buy the Reactive versions of those as soon as they are available… hint hint! The 5mm Reactive is as warm as the standard 7mm farmer john I had been using the week before… but with FAR less lead needed. Love it!

What a great wetsuit

I have had this wetsuit for about a year. It's great! It's been in caves in Mexico. 65m tec dives in Indonesia. Summer dives in California. It's even been in Lake Mead near Las Vegas. I am happy with it.
