The Winter Active WSP Pants are made from a soft, highly stretchy fabric and include a Gore-Tex Infinium™ membrane that blocks out the wind as the weather approaches. The membrane is also Bluesign® certified, which guarantees that it is produced sustainably. The pants are camouflaged with Härkila's own AXIS MSP Snow® camouflage, an improvement of our popular AXIS MSP® design. The pants have also been given a dirt and water-repellent DWR coating. With any active winter hunt, it is critical to wick as much moisture away from the skin as possible. This is one of the spearheads of the design. The pants are not only wicking and highly breathable, but also have zippered ventilation openings on the back of the thigh. The vents are lined with netting to keep out snow when unzipped. The trousers have two large zipped thigh pockets and a 4-round cartridge holder on the right thigh. There are adjustment straps behind the knees for an optimal fit. There are adjustable snow locks at the ankles, so that they close tightly around your boots. There's also a hidden hook at each ankle to attach to your shoelaces to prevent the trouser legs from riding up when you're out in the snow.
