BARE drysuits don't shy away from high-demand technical diving or from recreational divers who simply want the best. Your favorites range from the X-Mission, our most technically advanced drysuit, to the HDC Tech Dry, our most durable suit. The women's Trilam Tech Dry has also become a favorite, because of its lightweight and flexible material, making it an easy diving drysuit. With the XCS2, our NST process (No Stitch Technology) uses double heat tape technology and âpin stripeâ tape to securely seal seams while maximizing the suits overall stretch characteristics. Inner fabric is a high stretch blend of nylon and spandex thatâs incredibly smooth, for easy donning over thermal layers.
