These fit great. I wore them all last week and felt better than the Smartwool Mediun Weight I have already. Long enough to shrink but not too long. I bought the blue ones

I ordered these and a crew, both lightweight. They are perfect for me in north Alabama. Following the size chart's recommendations got me a good fit.

They are so comfortable that I have found myself not wanting to take them off. Amazingly comfortable, much different than the wool I grew up with.

Plenty warmth for my part of the country. I'm hooked.

I could not be happier with these. They are super soft. Unbelievably comfortable. The seams on other base layers I have worn have bothered me. I don't even notice they are there on these. Warmth wise, well they are a lightweight pair. Although, they are warmer than other lightweight layers I have tried. Perfect for snowboarding or other winter activities during a Utah winter, which is exactly what they are made for. However, not the best for high mountaineering unless you have some other significant layers on.
