[ I was looking for wool thermal layer for my husband, who runs cold. Rather than settling on a bland look, I chose this colorblock version for its added style. While he does n't fill it out quite as nicely as the model(!), he looks great in it.

[ I bought the Smartwool to keep me warm and comfortable on a 12 day trek in Nepal. The performance was outstanding and, as advertised, it was very breathable to keep me warm and even cool in the afternoons. It has a very comfortable feel and looks great as well.

[ Nice casual soft base layer. Very thin and lightweight. Nice color and decent price on sale.

[ This is a great shirt. Super soft and light. Great for travel and as a base layer for chili days or evenings. The only gripe is that I bought one of these a year ago, size large. When I bought the most recent one the large was now too tight. So I bought an extra large. Body fit is now great but sleeves are long!!

[ Great quality as always with Icebreaker. I use this shirt for Summer outings to avoid using too much sunscreen, yet keeps me cool enough.

[ I have 2 previous versions sphere ii long sleeve t shirts that I wear on summer hike. I like them even if their material is not strong enough for hiking trips. one of them have a few small holes after laundry. this version seems to be stronger because material is thicker. another difference is sizing. I need M size in contrast of S size from previous version.
