Smartwool Men's Midweight Merino Wool Zip Neck Base Layer Top - Warm & Breathable for Hiking, Skiing & Outdoor Activities

I am a huge fan of the smartwool brand and they did not disappoint here. First I have to note though that I am a female that had to purchase a men's version in order to get the proper length. I tried three different smartwool female versions and all of them were shorter than I like (I am 5'11"). I now have two of these midweight tees which are a great layering piece as well as just a throw-over, heading out piece. They keep me nice and warm while still being breathable. Plus there are the natural benefits of the wool which are great. Overall, very pleased. Now if they could only do the same for the female versions...
