Fourth Element X-Core Vest: Maximum Thermal Protection
The Fourth Element X-Core Vest provides a highly effective solution for divers seeking significant extra warmth. Furthermore, it serves as an excellent alternative for those considering electrically heated products.
This minimalist vest delivers extreme thermal protection right to your core. Consequently, you can enjoy longer, safer, and much more comfortable dives.
Fourth Element designed it to be worn successfully under a Fourth Element Arctic or any other drysuit undergarment. Therefore, every diver aiming to extend their season successfully will find X-Core Vest invaluable.
No Batteries. Just You.
The X-Core Vest maximises your body heat retention, specifically addressing the need for more warmth.
Emerging research now suggests that active heating systems may present various physiological problems. Your body naturally produces about 100W of power, similar to a bright, hot incandescent light bulb. Most of this considerable energy is naturally dissipated as heat.
Significantly, the Fourth Element X-Core Vest effectively traps some of this heat within its dense fabric fibres, insulating your body core and maximising overall comfort.
X-Core Vest is Designed for Diving
The Fourth Element X-Core Vest performs perfectly next to the skin or layered over a baselayer, such as the Fourth Element Xerotherm or J2.
All-way stretch fabric ensures a snug fit across the torso. Crucially, the sleeveless design prevents bulk around the arms, allowing complete freedom of movement for necessary valve shutdowns.
Additionally, the long body section provides excellent coverage and efficiently prevents the vest from riding up. We make the X-Core Vest from 76% recycled post-consumer plastic waste, yet its high performance remains absolutely uncompromised.
