I just opened the package and it's exactly what I though it would be.  I live in Minnesota and work outside all year round.  I have always purchased Merino wool for my base layers.  Wasn't until recently, I figured what the heck, I may as well try the underwear type stuff.  I purchased eight pair of the WoolX mens boxers and absolutely loved them.  I bought these two Tees to check fit and feel.  I will be buying more.  I found the sizing to spot on.
