Our answer to the electrically heated vest or undergarment. Utiltising the body’s own heat output and retaining it, weight for weight the X-Core is our warmest undergarment yet. Pair it with an Arctic, Halo 3D or Arctic Expedition to experience warmth without batteries or wires.

The sleeveless design of the vest minimises impact on buoyancy and overall bulk especially in the shoulders and arms where freedom of movement is critical. The four-way stretch fabric combined with long body design ensures a snug fit, minimising cold points. The additional chest panel helps to minimise the rush of cold air from the inlet valve and provides extra thermal protection in a key exposure area. The fast wicking fabric moves perspiration towards the outer surface, keeping the wearer drier and warmer.
