Tough stuff, for great days out.
Stretched and snagged, burned and torn. To perfection. Polartec® puts every batch of its fabrics through the wringer to make sure they’re up to scratch for demanding surroundings. Like up a mountain – or January in Sunderland.

Polartec® Alpha®
Insulation that actively regulates warm and cool air – no more taking layers on and off during stop-start journeys or in fast-changing temperatures.

Polartec® Thermal Pro®
The squeeze of a soft fleece – with extra air pockets to trap warm air. And it’s extra-breathable, for all-round comfort.
