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. I_foam neoprene, which enhances flexibility even further, while Drygrid reduces the overall weight due to less water absorption. 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.
