Crafted with lightweight, stay-cool fabric, this stretch-fit design is tailored to perfection, so you can step into wherever the day takes you with renewed confidence and ultimate comfort.
1. If you are a slim or athletic guy with no extra weight in the belly: Use the chest measurements as a guide for picking your size. NOTE: your chest size = American sport coat size (eg. 42R = 42 inch chest)
2. If you have a little extra around the middle: First make sure that it fits you across the waist/midsection. Keep in mind that the shirt tapers towards the waist/midsection. NOTE: the "waist" is not your belt / pant size. It refers to your midsection around the belly button.
3. If you don't want your shirt to fit closely, feel free to "size up" one size for a looser fit. If the shirt fits you in the waist and is slightly big in the chest it is not the end of the world. It will still look good.
