I've had one heck of a time finding thermal shirts for my husband.  He complains about every one I've bought him in the past and made me return them.  I was ready to just give up and let him continue wearing his worn out, holes in them shirts.  He is not one to go out and buy clothing of any kind.  NOW I'm a star in his eyes because he loves these!  You'd have thought I gave him a million dollars!
