This is just a great t-shirt and that's that. I would call it a mid-weight material, certainly not the lightweight type that is so popular now, or the thick heavy material that makes you sweat like a student athlete in a calculus class. This t-shirt is just the right weight for most activities and situations. I'm 5'11'' and weigh around 172 lbs and medium fit me perfectly. Not too tight but not the baggy gangster look either. And the length is great too - not too long. Some folks will whine about the price but this shirt is made in America not in some sweatshop in China or Vietnam. So you are paying for American workers who get a paid a reasonable wage and for a company that has to comply with OSHA regulations and other important rules. That alone is worth the extra few bucks. The shirt is well made and the design is top notch - I get a lot of compliments on this t-shirt every time I wear it. So stop reading reviews and buy one of these shirts already - you will be pleased!
