Hidden inside these men's fur lined snow boots is a quality fur-lined inner that stays warm in temps as low as -25 degrees Fahrenheit. Special thanks to modern technology. Our men's snow boots sport thermolite insulation and 200g high-quality cotton. Not to mention the TPR outsole made out of the good stuff, seam-sealed and waterproof with a protective toe cap. An outer wrapped in water and wind-resistant fabric. We challenge you to pick an adventure and take these boots along for the ride.
