The Ascender pant is a burly mountaineering soft shell pant that can shrug off the worst of the weather & has functional design elements to ensure comfort & reliability when you are out in all weathers. They are made with a mix of heavy weight & mid weight DWS (Double Weave Stretch) softshell fabric which uses tightly woven Nylon & Polyester fibres to repel wind & rain whilst maintaining superb breathability. Larger fibres on the inside of the pants actively wick moisture away from your skin to the smaller, tightly woven fibres on the outside where it evaporates. These external densely woven fibres reduce wind & water penetration making these versatile pants remarkably weather resistant & very quick drying. The Spandex content gives the Vector Pants some stretch to allow for unrestricted movement & comfort. High wear areas on the knees & seat are protected by heavier weight DWS, whilst the rest of the Ascender Pant uses mid weight DWS. Reinforced instep kick patches help to reduce crampon & boot damage further enhancing the Ascenders winter mountaineering pedigree. A really nice feature is the Tricot (brushed) lining to the waistband that feels great against the skin & helps to wick moisture. Plenty of zipped pockets finish off these versatile & hard wearing mountain pants.
