These things rock. I wear a very minimal base layer and I stay toasty in even windy, cold conditions. Not to mention, they have a great look.
I love this Sidewinder SV shell. My only concern is with the see-through compartment on the arm built for season passes. The material is shaded too much for the pass to be able to be scanned. They should have used a clear material instead of the shaded material. It is kind of a bummer to have a jacket that costs this much and not be able to utilize the pass holder.
