THERMAL WARMTH OMNIRED Infrared Technology applies 13 thermo-reactive minerals woven into the suit's fabric to convert outbound body heat into infrared energy and reflect it back to your body. Infrared energy has been proven to improve the body's circulation. Increased circulation improves oxygen levels in the body, enabling you to use less energy, improve overall warmth and increase your time in the water. FIT, FEEL, COMFORT Nixie Ultra incorporates our newly advanced Progressive Full-Stretch technology that uses the latest in full-stretch neoprene by placing varying degrees of full-stretch panels into specific performance zones of the suit to improve fit, feel, comfort, and overall performance.
