The North Face Women's Thermoball Traction Mule II

Whether you're hunkered down at base camp or shuffling through the snow to refill the bird feeder, you'll love the warmth, comfort and grip of this ThermoBall slip-on. The recycled, ripstop upper resists water, ThermoBall insulation delivers down-like warmth even when wet, and the high-traction rubber outsole is equally suited to outdoors or in-tent use.
