I ordered two pair - size small - I own one pair - small in a slightly heavier material that fits well - but the two that arrived today are too tight- and the material is not very elastic. I am returning them and I am pretty disappointed.
Smartwool needs to be consistent with its sizing. I had the same problem with socks - some fit well - some are too tight -
