Rated 5 out of 5 by from BUY WOOL!!! I have used this product daily and hiking. I can't believe how well it performed and how I didn't smell after one day of use. I use synthetic material and after a few hours it smells. This shirt did an amazing job.

Rated 5 out of 5 by from Can you make a bicycle jersey like it? Fits great. Looks great, and offers excellent light-weight warmth. Very pleased.

Rated 5 out of 5 by from No Sweat, Finally I have skied with a poly base layer for years, but for some reason given the temperature range on the slopes this year, I found my self in a damp base layer getting chilled. Sean at Christy Sports in Vail suggested Smartwool and I have been delighted with the results. Better wicking, no soggy bone-chilling dampness and comfortable, no itch fit. I will be hiking with this base layer as soon as spring come along
