Exploring outdoors in cold weather calls for technical solutions. Our winter trousers feature taped seams, YKK AquaGuard® zippers and a PFC-free membrane that keeps wind and moisture out while maximizing breathability. The generously sized ventilation zippers help cool you down when you’re building up a sweat and strategically reinforced areas make the trousers extra durable. With adjustable leg openings our winter trousers fit easily over ski boots as well as hiking shoes, making them some of the most versatile outdoor trousers around.
