|The ThermoFlex is Xcel's most advanced diving wetsuit series, featuring all new TDC Thermo Dry Celliant, a revolutionary inner lining with Smart Fiber Technology that recycles your body heat into infrared energy for greater warmth, increased endurance, faster recovery, and enhanced overall performance. The 7/6mm ThermoFlex features TDC in a high pile diamond print front and back body from neck to knees, and a low pile infrared print from the shoulders through the arms. This 7/6mm is the only ThermoFlex with a semi-dry back zipper, plus Xcel's exclusive Drylock wrist seals that keep more water out and form a snug, comfortable seal. On the outside, tonal printed shoulder graphics reduce wear and tear from BC straps. The ThermoFlex is glued & blindstitched with compression-resistant UltraStretch neoprene for softer foam and better durability. Easy on/off ankle zippers with GlideSkin lined inner dams allow for extra easy access and comfort making this a great all around dive wetsuit.
