ION Base Semidry 4/3 BZ DL was specially designed for use in surf schools. Extremely robust material, Double Line GBS, Supra_Tex on the knees, and a special nylon adhesive in the calf area protect the material when stepping on.
All ION GBS Semidry suits (long arms and legs) have a Water_Gate_Plus batwing panel on the inside of the back zipper. It acts like a protective wall and keeps the water that has seeped in through the zipper away from the body. In addition, the glued blind stitch seam is masked with an additional neoprene tape to increase the waterproofness even further.; Heel protection and extra nylon protection in the calf.
