The three-layer construction includes a soft fleece interior for comfort, a breathable windproof membrane, and an elastic outer layer for a secure, unrestricted fit. This undersuit offers thermal protection under wetsuits and dry suits and serves as a versatile base layer for scuba and other water sports.

With UPF 50+ sun protection and defense against light friction, the Ultraskin undersuit supports long dives and surface intervals alike. It pairs well with other scuba gear, enhances layering efficiency, and manages moisture to keep you comfortable during extended dives and activities in the water.
