Most thermal layers force a compromise — warm enough to sit still, or flexible enough to move. The Base Layer Set drops the compromise. The fleece-lined interior traps warmth against your body from the first minute, while the compression cut gives full freedom of movement without the fabric slipping, riding up or bunching under whatever you wear over it.

A long-sleeve crew-neck top and full-length bottoms in one purchase — matched thermal level, matched colourway, no cold gap where a standalone top ends. Whether you put it on before a winter walk, a day's skiing or a morning hunting, the set disappears under your other layers and stays out of the way until you come back.

Key Features

• The fleece lining traps warmth directly against your skin from the first minute, not after the first half hour of movement.

• A compression cut keeps every panel close to the body — no bunching or riding up under a waterproof jacket, softshell or hunting jacket.

• The 2-piece matched set delivers thermal coverage from shoulder to ankle in one purchase and eliminates the cold gap where a standalone base layer top ends.

• 95% polyester stretch fabric manages moisture during active use and moves with you without pulling or restricting arm or leg extension.
