The textile cover on the entire bootie is treated with a nano-scale hydrophobic coating that repels water and mud on contact. This keeps the textile exterior surface of the boot from icing up in freezing temps and from retaining water in the fibers in wet conditions. With HYDROKOTE, soggy boots are a thing of the past. Water rolls off the nylon outer and dries in seconds keeping the exterior textile from icing up and from retaining water in the fibers in wet conditions. ROLL-DOWN CALF PIPE - Roll down the top to tuck in your pant leg or vent in warm temperatures.
