Designed to be worn under Fourth Element Arctic Expedition/Arctic thermals, this new design actively traps the bodies heat maximising retention. A must have for cold water or winter diving.

Tried and tested by our very own instructors, the X-Core actively traps body heat to maximise retention. Weight for weight, X-CORE is Fourth Elements warmest undergarment ever. The minimalist vest provides extreme thermal protection to the core, enabling longer, safer, more comfortable dives. Designed to be worn under an Arctic, Arctic Expedition, HALO 3D or any other drysuit undergarment, this is a product for every diver looking to extend their season.

The X-CORE vest is perfect next to skin or over a base layer 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.

X-CORE is an OceanPositive product. Keep warm this winter and do your bit to help our loved dive environment.
