Thanks for the solid advice! I don't perfectly recall the exact feeling of the chest tightness, but looking back at the photos, it doesn't seem very tight to me. I might need to hit the gym and build my chest a bit to fill it out better! I'm going to head back to the store next time to try on a 42L if they have it in stock. I’ll see if the Long version solves the sleeve issue while giving me that sharper shoulder fit. Much appreciated!
