These are fine for traveling in the flats and on very low grade slopes, but if you plan on going up any hills, get some Black Diamonds. I bought these skins about a month ago because my Black Diamonds were getting way to old and used up. I have enjoyed using G3 skis in the past so I thought I'd give the skins a try. Terrible waste of money. Used them three times for three of the most frustrating tours of my life, I ended up bootpacking each time. These skins gripped the snow about as well as a hot knife grips butter. Went back to using the old BD's.
