We've had a hotter summer than usual, so I decided to add a pair of short sleeve shirts to my wardrobe: the Arrow Men's Slim Fit Short Sleeve Shirt and the Arrow Men's Slim Fit Short Sleeve Shirt. shirts as they were very similar. I was just as comfortable in one shirt as the other, but the regular fit seemed a little better. Both were cut loosely, which is how I like shirts, and looked well pressed. Both are thin, light and stretchy and I'm still wondering how they do that as I don't see any elastic in them at all. . They are elastic in the "bottom" of the shirt, but not in the area of the collar, pocket or buttons. uncomfortable in regular fit. I will not be wearing a tie with any of the shirts so this was just for verification. Overall I liked both shirts and would recommend them if you are looking for a light summer shirt with short sleeves.
