The worst thing about this product: Putting it on and taking it off The best thing about this product: You literally always wear it! long and figure-hugging, so putting on and taking off is very cumbersome, especially with long hair. However, they hold up great, are warm, do not move and do not slip off. I use them when ice fishing and they make my face and neck very comfortable.
