Fourth Element X Core

EXTREME THERMAL PROTECTION

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.

Combining heavyweight Polartec® Powerstretch® fabric with thinner fabric in key areas to minimise bulk, provides the critical core areas with the enhanced protection of X-Core, whilst making the leggings easy to layer up underneath an Arctic. A lightweight waistband avoids too much bulk around the midriff, whilst the insulating material extends to just below the knees for exceptional thermal protection, especially when on trim. Bulk is minimised in the lower legs and behind the knees for maximum mobility. Fast wicking fabric makes this an excellent next-to-skin layer or can be used with an additional base layer
