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.

Wanna know if you are a true hero on the water?
Just check out the ION Hero_Meter on the left wrist of your FUSE drysuit! It will tell you roughly the surrounding temperature and the equivalent hero-level … OK, frankly this feature is more a little fun gadget, but we love it anyway! By the way, if you don’t know Ötzi, just google it …

Visual safety feature for FUSE and ENVEE drysuits: 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.

The ultimate answer to a full bladder in a drysuit when it’s f** 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 tap can be stored hidden inside the opening above, so nobody will even notice it’s there.

Only super flexible SEAMTITE® LatexCuffs 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 GlideSkin inside similar to our Onyx models to improve warmth, wearing comfort and avoid choking.

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.

High resistance against abrasion.
Great strength against tearing.
Primarily used on knee panels or buttock area


All wetsuits that have the Water Gate Plus batwing panels have small holes in the lower back. This keeps the back area dry by allowing the water which has leaked in through the back zip to drain out. DrainHoles are also placed in the calf area to prevent water from getting stuck in a 'bubble' like fashion. In addition to this, ION front zip wetsuits also have DrainHoles in the chest and back panels.

No need to panic! All ION wetsuits are equipped with a clever key pocket, inside of which is an elasticated attachment. Depending on the model of the suit, this feature can be found on the calf, arm or other area. *Please note. Only store water resistant keys in order to avoid any damage.
