These are very comfortable shirts.  I bought 2 the first time, Loved them so much I bought 3 more.  They are perfect in their comfort and very well made.  The love the stretch in the fabric, it moves with me, not against me. Doesn't bind and is cool and warm, I can't explain that but its not a ramble, the shirt is like relates to your body temp and reacts one way or the other. Very nice quality t-shirt. Could use it a a layer too.
