Narrow sleeves, but great other than that.
Just received this shirt and liked everything about it, except the sleeves are too narrow. I couldn't roll them up over my arms, I'm not a particularly big guy (6', 210) but I have some muscle. (Well, at 60, a lot less than I used to 😞) So, I just ordered the XL - hopefully that'll do the trick.
Yes, I recommend this product.
