Made in the UK since 1979, the Double P System pairs a tightly woven Pertex shell that blocks wind and sheds showers. Underneath, a fibre pile lining traps warm air and wicks moisture outward. One layer that does the work of several. Relied on by mountain rescue teams and the military for decades. Shop the pieces people keep for twenty years, alongside this season's new additions.

Explore Buffalo outerwear for men and women, built to handle wind, rain and cold without the need for extra layers. The collection is led by the Mountain Shirt and the Smock, alongside seasonal jackets, gilets and layers added throughout the year.

Each piece pairs a windproof, water-resistant outer with a soft pile lining designed to be worn next to the skin, keeping you warm, dry and comfortable whether you're on the hill, on the water or out in everyday weather. Lightweight, packable and made to last, it's outerwear that works as hard as you do.
