The K2 Extreme Steamer Cold-Water Thermal Protection Full Mens Drysuit Undergarment is designed for drysuit diving in cold water. It uses a breathable, stretchy dual fleece material to deliver warmth while preserving mobility for scuba, diving, and underwater adventures. The one-piece steamer design provides full coverage with anti-squeeze padding for the shoulders, chest, and knees, enhancing comfort during gear-intensive dives. Weight is approximately 3.086 lb (1.4 kg).

Storage pockets with zippers are located on both hips, and elastic wrist loops along with heel straps help prevent ride-up when donning a drysuit, keeping the base layer secure during underwater excursions. Compatible with trilaminate drysuits, this undergarment supports reliable warmth and performance as part of your scuba gear.
