I have been wearing Helly Hansen base layers for over twenty years (bought from LL Bean). They are perfect products.
My ONLY word of caution about the Ice Crew is that it may well be TOO WARM. It is advertised for extremely cold weather use, and I agree. Wearing this under a leather jacket on a motorcycle at speed on a thirty degree day keeps me not simply warm, but hot.
So, it is good if you need warmth on really cold days, but is probably too much on simply chilly days.
