Eliminates blue lint in every wash - for a lifetime. Short for my long arms, but I usually roll up my sleeves, so it doesn't matter. The neckline is 2-3 inches smaller than the button above, but I will never wear this shirt with a tie anyway, so it doesn't matter. I have several of these shirts and they are the main shirt I wear. Awnings... and awnings... and awnings. I expect they will eventually wear out, even for my more casual tastes, and need replacing. I don't have any other clothing or underwear that tends to shed much, other than new towels for the first few washes, so I'm sure shirts can be made out of longer fiber cotton, but these aren't shirts.
