01 / WARMTH

Holds your heat.

Fleece-lined thermals retain body heat close to your skin. Warmth without the bulk, underneath the rest of your day.

02 / SOFTNESS

Fleece where it counts.

Ultra-soft fleece lines the inside of your set. Soft against your skin, from the first thing you put on to the last hour of the day.

03 / MOVEMENT

Moves when you do.

Four-way stretch moves with you as you bend, reach and get on with your day. A close-fitting first layer with room to move.

04 / DRY COMFORT

Breathes as you warm up.

Breathable, moisture-wicking fabric moves perspiration away from your skin, keeping your first layer comfortable as the day picks up.

Made to layer.

A close-fitting first layer under jeans, workwear or a ski shell.
