My son "borrowed" mine to use while snowmobiling and won't give them back. He absolutely loves them. They are waterproof, and the seam-sealed construction is made from a waterproof synthetic leather and nylon textile. The draw string on the top keeps snow from coming overtop of the boot. They have a SUPER warm reflective removable linerc will provide all day dry comfort against the cold snow conditions. Very durable boot and the sole has deep, lugs for excellent grip. I will buy again - especially because I don't think the kid will be giving mine back. He loves them.
