The Xcel Women's Infiniti 4/3mm Back Zip Fullsuit Wetsuit is Xcel's dependable cold-water fullsuit built for women who surf — engineered for core warmth and all-day comfort in water temperatures from 52–62°F (11–17°C).

• Neoprene: Nanoprene Lite Japanese limestone neoprene — lighter, more flexible, and warmer weight-for-weight than petroleum-based neoprene
• Chest & Core Warmth: Thermo Dry Radiant (TDR) interior from chest to ankle — locks out cold water while reflecting body heat back inward for sustained warmth through long sessions
• Upper Interior: Ultra Stretch Infrared (IR) lining — lightweight infrared warmth in the shoulders and upper body for range of motion and warmth where you need it most
• Exterior: All Channel Flex exterior paneling — maximum stretch across the back and shoulders for unrestricted paddle stroke
• Entry: Back zip with super-sealed seam construction — reliable closure with fully waterproof seam bonding throughout
• Fit: Engineered women's fit with glide skin collar — anatomically shaped for comfort and zero neck chafe through extended wear

The Infiniti 4/3mm is Xcel's everyday cold-water suit — not the most premium they make, but dependably warm and well-constructed for regular sessions in winter conditions. The TDR core lining is the key warmth feature: it traps a thin layer of water and holds it warm, rather than flushing cold water through the suit on duck dives.

Sizing: Xcel wetsuits run true to their size chart. Measure chest, waist, and height and cross-reference with Xcel's women's size guide. A proper-fitting wetsuit should feel snug throughout with no dead air pockets in the torso.

Care: Rinse thoroughly inside and out with fresh water after every session. Hang to dry on a wide wetsuit hanger away from direct sunlight. Do not machine wash, tumble dry, or leave crumpled wet in a bag.
