This is not the typical fit of a tshirt.  We have purchase mock neck tshirts in the past from other companies and my husband loves them.  They normally have the same fit as a regular tshirt but with a mock neck.  This one is a very tight fitting shirt all over including the mock neck.  I'm sure the quality is good as Jockey is a great company, but the description needs to be updated.  If you are looking for a really tight fitting shirt from sleeves to neck to chest to stomach, this is for you.
