Built from a 3-layer GORE-TEX ePE recycled polyester, these overtrousers deliver excellent waterproof protection and breathability with a 28K/<13 RET membrane. A 3-layer stretch polyester hem with DWR treatment combined with a 20K-15K fine-knit nylon layer adds strength while remaining flexible. Side openings with divisible zips allow for quick access to layers and increased ventilation during strenuous, uphill sections. And a pull-on-style stretch waistband with adjustable drawcord allows for easy on and off. An under-shoe attachment ensures the gaiters stay in place, too. Securely store small essentials in the zipped side pocket. The unisex Reactive Cover Pants equip you for year-round mountaineering and trekking outings.
