      My husband loves these! Perfect gift for him. Wish they weren't so expensive but if will keep his feet warm while sitting in a tree stand then it is worth it.

      The only thing my boyfriend dislikes about them is soft battery cover shifts over short period of use, otherwise it's decent product.
