These woollen base-layer trousers are designed to provide an essential heat-regulating layer for demanding activities. Made from 100% breathable merino wool, the 3/4 leggings boast all-natural moisture management and insulation, while remaining breathable. That means you stay comfortable even while powering up steep inclines. Superfine yarns also create a soft, cosy feel. The stretch waistband makes this base layer easy to pull on. And it keeps the trousers in place when you're picking up speed or navigating a tough section of trail. The Merino Concept 3/4 Pants for men are an essential base layer for cold-weather runs, winter walks and snowy adventures.
