Patagonia built the lightweight and breathable Women's Wind Shield Hybrid Pants for trail running, climbing, hiking, and other cold weather, high aerobic activities. A DWR finish on the comfortably stretchy softshell fabric provides protection from wind and water, so there's no need to be scared of a little rain. An external drawcord provides a customized fit for ultimate comfort while you're tearing up that trail. Breathable Capilene Thermal Weight fabric panels on the side and back allow excess heat and moisture to escape, letting you go all day in airy comfort, while the Polygiene treatment keeps nasty odors from building up. Reflective icons behind the knees and a reflective hip logo deliver visible safety for those early morning or late evening runs, and a zippered back pocket with key clip keeps your essentials secure.
