Thanks thats exactly why I was asking because the Iron heart shirts have small shoulders and bigger chests, but flathead has a smaller chest and bigger shoulders.  Though, I think if I go with the L I should be good so I am ordering my first Iron Heart shift now! Thanks DrPat.

I did compare the measurements and the L looks like it would be probably the choice for me thanks tho.

So I wear a 42 in TFH saw tooth denim shirt and i prefer a little bit of a slim look. Should i go with a M or L in the black?

Currently I have 2 tattoos, one of my Yia Yia (greek for grandma) name in greek on my upper right arm.  The other is a ship, though I am turning it into a sleeve starting december 3rd. Post pictures of finished product.

New to the forum, but I am very happy to say I am from Los Gatos, CA!
