"What Our Gearhead® Experts Are Saying:""These pants are my pick for tough days in the mountains. The reinforced knees and seat hold up to scrambling, while the stretch panels keep me moving freely. The full-length zips are perfect for ventilation or slipping on over boots.""From windswept ridgelines to long days on the trail, the Falketind Flex1 Heavy Duty Pants are built for all-season durability and mobility. Recycled plain-weave nylon delivers wind resistance and rugged performance, while flex1 softshell panels on the knees, seat, and thighs offer stretch, breathability, and moisture management. A PFC-free DWR finish sheds light rain and snow, and the articulated knees ensure comfort on steep ascents and technical moves. The custom-fit waist system provides a secure fit, while full-length, two-way side zips make layering easy and allow adjustable ventilation. Reinforced panels and gaiter hooks add to their mountain-ready versatility, making them a trusted choice for trekking, climbing, and even light ski touring."
