Just an FYI, that's a different Black Diamond from the company that makes all the cool climbing and ski gear. Not that those are bad softshells, but they aren't the same as what you'd get from www.bdel.com
Consider this somewhat of a bump as they are still at Costco.
As mentioned above, I bought two. Although I have not been able to use them skiing I have used them for riding my motorcycle. I have used one several times now in 65-70 degree weather when riding my bike. I realize 65 degrees does not sound cold but 65 degrees at 45-70mph with the wind chill factor and riding without a windshield (yes, I said without a windshield. Its a Harley thing...) I was very impressed with how well they block the wind yet when I would stop riding and wear it around taking care of business I was not over heated.
They also work great in the cooler mornings for horse back riding... $26 is a steal!!
