These shirts feel like they're high quality but the sizing is weird.  I wear an XXL undershirt in every other brand I've ever bought.  These XXL shirts are HUGE.  Way too big, even after being washed in hot water.  I also tried the XL size (washed in cold water) and they're way too small.  There's too big of a gap between XL and XXL to be useful to me.  I'm taking both of them back...
