The shirt appeared to be well made with just a touch of spandex.

I know it's all the rage to let your undershirt show, but it's not a look for me.  If you need a v-neck that will remain hidden behind an open-collared dress or polo shirt, then keep looking.  The v-neck is cut too high on these and will show.  (me: 6'1", 205lbs, 46" chest; shirt: size XL).

These went back to Amazon immediately after seeing how high the v-neck was cut.
