65 poly 35 cotton. i agree, you might want to order the next size up. i found the size on the mann lake jacket to be true, but a little more room makes it cooler in summer and lets you wear more in winter if you need to take a peak.
i don't know if KONASDAD is recommending no face protection? i would say that a veil is something you should own if you don't have a combo outfit. stings to the eyes, nose, etc. can be very dangerous. eye stings require immediate medical attention, and airway stings can cause you to swell and not be able to breath.
i swell like crazy, so i always cover up. some choose not to, and thats ok. you should probably know how you react before you make that call.
PS....JP didn't mention that thing about close fitting clothes until after i had done a cutout in tight jeans! you will get stung through the clothes if they are a tight fit and your bees get aggravated enough!!
