This wetsuit is very comfortable and easy to move around in. The OS stands for "offset" and that refers to the zipper. The Xcel 3/2mm OS Zip Wetsuit has an offset zipper that gives you more comfort and less friction around the neck. With pre-bent elbows and knees, you are sure to move around and perform at your best. There is a heat retaining lining made out of bamboo charcoal fibers so there's no freezing in this one. This wetsuit is durable and it will last you a long time.
