The Amaze Amp is the premium wetsuit in the ION range. It stands for epic stretch. Ultra-flexible thermal lining combined with lightweight neoprene provides extra warmth for uncompromising freedom of movement all year round. The secret for optimal heat retention lies in ION's super-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 insulating air thanks to a new structure that contributes to better heat retention and flexibility. In spots without thermo lining, super soft Silk_Stuff increases next-to-skin comfort to the max. Amaze Amp Backzip models feature additional protection pads at the shins as well as detachable leg loops to prevent water from rushing into the suit.
