Fuse Drysuit 4/3 Back Zip - 215/501 grey/red
Keen on riding in sub-zero temperatures? ION's Fuse Dry Suit was designed to withstand even the fiercest conditions. With safety in mind, we did not only focus on superior warmth but also made sure you get all the security gadgets you need on dark & stormy days. Focus on your riding with peace of mind, knowing the Storm_Whistle & reflective prints increase your visibility if things go south. Water-proof zips, taped seams and sealing latex cuffs guarantee a dry ride while the baggy fit & adjustable, detachable hood add up to comfort and mobility. Eventually, each suit has to pass ION’s rigorous testing of the waterproof diving drysuit seams before leaving the factory.

Ever tried to call for help in a roaring storm? Difficult! That’s why we looked for the loudest safety whistle on the planet and found it: The Storm_Whistle®! This incredible whistle is twice as loud as any other mouth-blown whistle in the world and even the US military, special forces and the police is using it. And the best thing is: it even works in and under the water due to its patented harmonic chamber creating the extreme 3150 hertz frequency sound.


Visual safety feature for FUSE drysuit: being out on the water in cold winter time can be seriously dangerous especially because it is getting dark much earlier. In case of an emergency you now can rely on additional reflective prints on the shoulder / hood area, which makes it a lot easier to be detected by SAR crew searchlights.

Adjustable hood

Multiple adjustments on the hood allow you to stay warm even in the worst conditions.

Detachable Hood

Metal free attachment of the hood to prevent the pushbutton get jammed due to corrosion.


Premium brand TIZIP Master_Seal® zipper prevents water from leaking in and makes the ENVEE drysuit highly waterproof for above-water sports like kiting, windsurfing, surfing, SUPing, etc. This VISLON quality tooth construction provides a smooth low-friction closing/opening and keeps out the water effectively. It is also much more flexible and needs less lubrication than other zipper types.


The ultimate answer to a full bladder in a drysuit when it’s freezing outside: This TIZIP Master_Seal® zipper (same quality as on the back) provides the crucial feature for a long day on the water. The easy pull zipper tape can be stored away inside the opening above, so nobody will even notice it’s there.


Only super flexible SEAMTITE® Latex_Cuffs by the premium brand SPECIALISEDLATEX are used for the FUSE drysuit on the wrists and ankles to prevent water leaking into the drysuit. The neck cuff is made of super soft and stretchy Neoprene with Glide_Skin inside to improve warmth and wearing comfort.
