Light Monkey heated underwear

This heated underwear is designed to be used as a base layer, allowing additional layers to be added as needed. So whether it's ice diving in the Arctic or springtime cave diving in Florida, this shirt will add minimal bulk to your current drysuit setup. Glued and sewn by DTEK in Italy using a ZeroWind® membrane, this makes the outer shell windproof and water resistant. The interior is breathable and wicks moisture away from the skin, preventing faster heat loss in the water.

Two thermal elements, each rated at 20W for a combined 40W of heat. Unlike traditional heating vests, these thermal pads use a silicone insulated carbon fiber heating element instead of wire, so they won't bend or break over time. The thermal pads plug into your drysuit bulkhead using an O-ring self-locking connector. When you're ready to wash your underwear, the thermal pads are completely removable with two zipper panels inside the shirt.

The garment is sewn by DTEK in Italy, and final assembly takes place in Lake City, USA. Machine wash inside out with warm water and mild detergent, and hang to dry. Do not tumble dry or dry clean. Do not bleach. Outer shell is 95% polyester, 5% rubber, inside is 100% polyester.
