After purchasing these myself,based on reviews,I feel I must WARN others about something. They are too small for average American male measurements. I usually buy XL in cotton tees. I usually pay anywhere from 5-7 dollars each,but they last a long time and are very comfortable. I don't care for polyester of any kind in my shirts.They are medium thickness,and when washed hold their size and quality. They are loose to the skin and may have a couple of inches of play around my mid section,so not tight. These were a good price,so I thought from HANES,why not. First of all XL was way too small for me. I am six foot 215 pounds,and the store bought XL fit great with room to spare. These were tight out of the box,and thinner than what I had been buying. We were going to send them back,but my wife said they would fit her if she washed them,so we kept them for her (due to the good price). They do shrink!! So now there is no way they would fit me,but they did my wife who wears womens small to medium (depending on the manufacturer) and the looseness desired. We don't like tight t-shirts. I would suggest at least a size up and if you want them "loose" go 2 sizes so after washing they will fit nice.
