A good quality heavy shirt, too warm for it at the moment though but come winter I can see it getting a lot of wear.

Nice heavy weight long sleeve shirt, fits well, wouldve liked if the neck opening was a bit more slimmer or smaller as it seems a bit wide for my preference.

One of the few shirts ive worn that make me feel comfortable to wear and not worry how the waist will look, tight and loose enough to be perfectly comfy
