The ION Amaze Core 4/3 Back Zip is a women’s wetsuit designed for everyday sessions in mild to cool conditions. Made from natural, neoprene-free rubber derived from oyster shell powder, soybean oil, and eco-carbon black, it offers durability, flexibility, and a lower environmental footprint.
The Hot_Stuff 3.0 thermal lining, made from recycled fibers, keeps you warm while maintaining stretch and comfort. A smooth Silk_Stuff 2.0 inner lining on the lower legs and sleeves enhances comfort and makes it easier to slip into the suit. With seamless shoulders and a reduced panel layout, the Amaze Core 4/3 ensures complete freedom of movement — whether you’re windsurfing, kiting, or catching waves.
Glued-blind stitched seams with flexible reinforcements at the knees and crotch provide long-lasting durability and water resistance. Additional details such as Water Defender Legs, reinforced drain holes, a key pocket with loop, and separate leg straps make this wetsuit a smart, reliable companion for every water session.
