Worn next to the skin or as your only mid-layer, the Buffalo shirt is where the Double P System really came to life. Fast-wicking pile and a windproof Pertex® outer keeps you warm even when you're wet and working hard. From the lightweight Windshirt to the award-winning Mountain Shirt. No faff. Built to endure.

The Mountain Shirt is the first garment that utilised Buffalo’s Double P System, taken from our earlier production of sleeping systems. Worn directly against the skin, its pile lining draws moisture away while the windproof Pertex® outer helps protect you from the elements. The two fabrics work together to maintain warmth through hard climbs, sudden rain and the slower moments when you stop moving.

The range gives you options for different conditions. Choose a lightweight Windshirt when you need protection from the breeze without much bulk, the Active Lite Shirt for fantastic year-round use, or for the award-winning Mountain Shirt and Special 6 when warmth and weather protection matter most. Trusted by fell runners, expedition climbers, Mountain Rescue teams and Special Forces, these are practical garments made for repeated use, repair and years of adventures in the great outdoors.
