Best purchase I have made in some time that I actually needed that I didn't know that I needed. I'm deployed in Afghanistan and it is snowing like crazy here, being proactive I decided to purchase this because I work on satellite dishes installed on very tall steep building roofs and I didn't want to slip off. Also, sometimes the need to duck and cover are important and I don't want to be slipping all over the place. So far, the performance and ease of putting them on are beyond my expectations. Great buy - Highly recommend!!!
