Product Reviews

Rated 5 out of 5 by from Lightweight But Warm [This review was collected as part of a promotion.] I was surprised how thin and lightweight this shirt was: not transparent, but not opaque, either. I have limited experience with merino base layers, so I wasn't expecting it to be super warm. I was surprised to discover I was wrong: the shirt provided a surprising amount of warmth, though it wasn't too much. Thermal regulation is exactly what I need. Looking forward to using it in a couple of weeks on the trail in Nepal! #sweepstakes

Rated 5 out of 5 by from I have purchased multiples of this item. [This review was collected as part of a promotion.] We live in the mountains--Lake Tahoe, CA--where the evenings get cold even in the summer. Depending on the season, I wear these either as the primary garment or under layers.

Rated 5 out of 5 by from lightweight, comfortable and effective [This review was collected as part of a promotion.] I have three of these in different colors and I have have five of these over the years. I like to wear them on a cool morning. They are lightweight but they keep you warm, the fit is excellent (not baggy and sleeve length is great), and the weave and texture of the wool is so comfortable. Great product

Rated 3 out of 5 by from Great product, poor delivery [This review was collected as part of a promotion.] I've had this product before and it is excellent. The problem this time is that the product never came. It became "lost" in the fedex delivery pipeline and it was up to me to figure that out. I even received review requests from Smartwool asking if I was enjoying my new top. Bottom line: Smartwool can't give an item to FedEx and then just forget about it. I finally canceled the order after it was several days late.
