More stretch than a standard Comp and warmer than anything at its price point — the XCEL Comp+ 4/3mm is the everyday cold-water suit that doesn't ask you to choose between warmth and flexibility. Channel Flex exterior — lightweight hydrophobic gridded material that breaks up tension and allows full range of motion in every direction Thermo Dry Infrared (TDIR) interior — exclusive XCEL heat-generating infrared fiber that delivers warmth without added weight or bulk Nanoprene Lite Japanese limestone neoprene — lighter and more eco-conscious than petroleum-based rubber; softer from the first wear Triple glued and blind-stitched seams + Fusion X tape — reinforced, watertight seams for durability across every stress point Glide Skin collar — smooth neoprene at the neck seals out water without chafing Thickness: 4/3mm — ideal water temp 52–60°F / 11–15°C The Comp+ sits right in the sweet spot: enough warmth for a proper cold-water session, light enough that you won't feel it after your first wave. The Channel Flex exterior bends with you in every direction, and TDIR lining keeps you warmer longer without the stiff, padded feel of older thermal technologies. Sizing & Fit: Runs true to XCEL sizing. Performance fit — use XCEL's height and weight size chart. The suit fits snug initially and relaxes slightly as the neoprene warms to your body temperature. Size up if you're between sizes or plan to wear a separate neoprene hood. Care: Rinse inside-out in fresh water after every surf. Hang to dry in the shade. Do not machine wash, use hot water, tumble dry, or fold when wet.
