The soft, plush, brushed fabric of the Saucony Men's Siberius Pants will keep you feeling great on even your frostiest of workouts. A straight leg fit and gusseted crotch offer supreme comfort during long runs, and lower leg zippers help these pants slide on over your shoes and give you some breathing room. An elastic waist with internal drawstring provides excellent fit, and gripper elastic at the back waist helps keep things in place. Zippered hand pockets keep essentials secure while the reflective trim helps people see you in low light conditions. To warn you when you need to do your post run stretching inside, the Siberius logo changes from white to blue when temps dip below freezing.
