The Tirill Hybrid Pant 2. 0 uses weather-protective, PFC-free DWR-treated fabric on the areas that take the brunt of wind and spray, with a brushed interior for comfort against the skin. A crotch gusset and articulated knee construction free up movement, and a wide, elastic waistband with an interior drawcord holds a secure, custom fit. What Our Gearhead® Experts Are Saying:"Wind-driven snow flurries never got through the front panel on a morning dog walk. For everyday cold and spray, the protection holds up exactly where it needs to."
