The Amaze Amp 3/2 Front Zip stands for an epic stretch without compromising warmth, making it the perfect wetsuit all year round. Stretchy material topped with a minimalistic panel design provides freedom of movement in the crucial arm and shoulder area. The secret for optimal heat retention lies in ION's super flexible Hot_Stuff 2.0 thermo lining combined with toasty warm Plasma_Plush 2.0. On top, I_foam neoprene traps more air due to its foamy structure, improving heat retention and flexibility. Another feature that shelters you from icy showers is a small silicone print at the front zip opening area. It increases the connection between the top and bottom opening of the flap. 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 stretchiest lining Hot_Stuff 2.0. Seam Sealing: Improved version of highly elastic neoprene tape securing every inch of lower body seam
