Stephen L.wrote a review of Black Diamond Ascension Nylon Custom STS Skins on February 29, 2012
I ordered and cut these down myself with no issues.
I put them on my fat teles and took a 5 day tour. They stuck to the snow like paint. They grab the snow so well, I am going to trim them to only cover about 60% of the base of my ski. If you trim them per instructions, and you have fat skiis, you have a LOT of skin on the snow....too much for me. They are quite heavy and you could shed some weight by trimming more. Also, you will get a little better glide with less skin on the snow.
