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 which contributes to better heat retention and flexibility. In spots without thermal lining, super soft Silk Stuff increases next-to-skin comfort to the max. Seek Amp Backzip models feature additional protection pads at the shins as well as detachable leg loops to prevent water from rushing into the suit. Features: Toasty Warm: Quick drying Plasma Plush 2.0 combined with Hot Stuff 2.0 for the best combination of warmth and stretch. Epic Stretch: Limitless movement thanks to less panels and our stretchiest lining Hot Stuff 2.0. Seam Sealing: Improved version of highly elastic neoprene tape securing every inch of lower body seams and highly stressed cuff area. Minimal Panel Design: Sweep Cut and a continuous panel on front and back are the reason why this suit feels like a second skin.
