Xcel Men's Comp X Full Wetsuit 4/3mm When Iconic becomes Legendary, the new Comp X is Xcel's flagship performance wetsuit, built for surfers who want the perfect balance of warmth, stretch, and comfort. An ultra-soft plush lining throughout the interior delivers next-level comfort while trapping heat where you need it most. Exclusive Thermo Dry Celliant (TDC) infrared technology reflects your body's natural energy back to help maintain deeper, longer-lasting warmth when the water gets cold. On the outside, Channel Flex/Material X delivers lightweight flexibility for unrestricted movement, while fully sealed seams help lock out cold water. A one-piece front and back panel design creates a more natural fit, reduces seam restriction, and improves long-term durability. From the first paddle out to the last wave, the Comp X is built to keep you warmer, lighter, and in the water longer.
