Review on Smartwool Merino Base Layer Black by Tim Duncan

I received this item on Tuesday and ran the last 30 miles of a 100 mile race with it on Saturday and Sunday. All day I've been sweating through my trusty old technical t-shirts. But after wearing it late into the night, I couldn't believe how well it kept me dry and at a comfortable temperature, even with a sweaty running vest. Bravo. I had no issues with chafing and if I needed to adjust the temperature a bit here and there I would unzip/unzip and roll up or down the sleeves. M thin. Fit was great, just washed and now dried. I hope the size stays the same over time. I will try to add Smartwool shirts with short sleeves to my range.
