Warm but quality control issue
Yes , I recommend this product
[This review was collected as part of a promotion.] Use it for cold weather hiking and biking. It is warm and cozy. The zipper does not work properly as I need to twitch it left/right along the upper end to make it zip all the way. The zipper is anything but smooth as the other icebreaker items including a cardigan are, that i own. For a size large it needs to be longer to work optimal as an undershirt. The material is superb.

Overpriced
No, I do not recommend this product
Outstanding warmth with top-notch quality, but at twice the price of other leading manufacturers that can match its performance. Will not return it but definitely will use my money more effectively in the future

Loyal icebreaker user for years
Yes , I recommend this product
[This review was collected as part of a promotion.] I wear icebreaker everyday but love it especially for my remote arctic whitewater paddling trips. Never fails, always warm, fast drying and comfortable. Love icebreaker
