This is Fourth Element's answer for someone looking for more warmth or considering an electrically heated product. Emerging research from DAN and other sources is beginning to show that there may be many more physiological problems with the use of active heating systems, so they have developed a product designed to maximise the retention of body heat.
The body has an approximate power of 100W (similar to that of a bright, incandescent light bulb - remember those and how hot they were?) and the majority of this energy generated is dissipated as heat. X-CORE aims to trap some of this heat in the dense fibres of the fabric, insulating the body core and maximising comfort.
DESIGNED FOR DIVING
The X-CORE vest is perfect next to skin or over a baselayer like the Xerotherm or J2. All way stretch fabric gives a snug fit on the torso, but the sleeveless design prevents bulk around the arms and allows complete freedom of movement for valve shutdowns etc. The long body portion provides excellent coverage and prevents the vest riding up.
