The ION Amaze Core 4/3 Back Zip wetsuits offers premium performance for an affordable price. We’ve upgraded this allrounder with Plasma_Plush thermo lining throughout the back area for increased warmth. In spots without thermal lining, super soft Silk_Stuff increases next-to-skin comfort to the max. Reinforced & sealed seams make the Amaze Core a very robust companion for your adventures. All Amaze Core Backzip wetsuits feature protection pads at the shins. On top, you can attach the Leg_loops to velcro to prevent water from rushing into the suit.
