Seek Amp stands for epic stretch. Ultra-flexible thermo 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 thermal lining, super soft Silk_Stuff increases next-to-skin comfort to the max. 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 fewer 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 the front and back are the reason why this suit feels like a second skin.
