Made from flexible material that feels soft and natural to the touch, this men’s base layer is perfect for running through cold winter nights. It can warm your body temperature by up to 3 degrees in cold conditions, so you can run just as hard when it’s chilly outside.

Get freedom of movement with stretchy raglan sleeves and a cosy, slim fit. The material has 7% spandex, so it’s great at recovering its shape.

• Keep warm with Motion Therm technology
