ION Onyx AMP Semidry 4/3 FrontZip
FREE poncho with this wetsuit! Poncho colour selected at random.
The ION Onyx AMP is the all-rounder with a classic tight fit for all water sports athletes looking for a wetsuit that meets their ambitious demands on performance, stretch and freedom of movement.
Increase your performance with the Onyx Amp’s perfect composition between stretch and warmth. The secret for optimal heat retention lies in ION’s proven flexible inside lining called Hot Stuff 2.0 in combination with toasty warm Plasma Plush 2.0 on the back panel. I Foam neoprene foam traps more insolating air thanks to a new structure which contributes to better heat retention and flexibility. In spots without thermo lining, super soft Silk Stuff increases next-to-skin comfort to the max. The result: Your perfect everyday wetsuit, no matter which conditions you will face today. Thanks to the front zip design, there’s nothing to interfere with your paddle power.

Unsure of your size? You can check out ION’s wetsuit size chart here.
80% Neoprene / 20% Nylon
Suitable for temperature: 11°C – 16°C, 52°F – 61°F
Toasty Warm: Quick drying Plasma Plush 2.0 combined with Hot Stuff 2.0 for the best combination of warmth and stretch.
Minimal Panel Design: Sweep Cut and a continuous panel on front and back are the reason why this suit feels like a second skin.
Replaceable Draw Cord: The cord is used to tighten the suit at the shoulder. The high load on this small detail can lead to unavoidable damage. Now it can be easily replaced. This is ION’s answer to planned product obsolescence that occurs in many other industries.
Separate Leg Straps
Plasma Plush 2.0
Premium lining offering the best of heat retention and stretch. The high pile fabric traps air for snuggly warmth and insulation while the vertically aligned channel structure transports moisture away quickly – for a dry suit after your break in between sessions.
Hot Stuff 2.0
The Hot Stuff 2.0 comes with a plushier feel due to larger loops that trap more air for heat insulation. It is the stretchiest thermo lining in ION’s entire range.
Smooth inside lining for a comfortable feeling on bare skin. Despite its snuggly appearance it proves to be really hard core when it comes to the interior’s superb flexible characteristics.
The I Foam is an extreme lightweight and stretchy neoprene foam. Thanks to the new foamed structure with more air trapped inside and a lower density the I Foam also contributes to heat insulation and better flexibility.
Maki Tape 2.0
Highly elastic neoprene tape reinforces the seams on the lower body and commonly stressed cuff area from the inside.
Seam-free shoulder design for increased paddle reach and shoulder rotation.
So let’s get down to the nitty-gritty: A soft cord lock for front-zip wetsuits that can be adjusted with just one hand. It’s a subtle addition that won’t bother you while riding.
All stress points are reinforced and secured by melco tape from the inside to ensure a longer lifespan of the seams.
Embossed sleeve and leg ends for a sleeker and more durable finish.
Again, this feature prevents water from rushing into the wetsuit by sealing off the cuffs and collar thanks to small rubber strips on the inside.
Quick water release when needed in order to combat water accumulation inside the wetsuit. The Drain Holes are secured in place from the inside and won’t expand.
Enjoy the session and stop worrying about your keys. Just store them in the Key Pocket inside the wetsuit. Please note, only store water resistant keys in order to avoid any damage.
