I was a little curious as to the size of these undershirts based on the 9-10T listed in the description. The size chart says they fit an 8-9 year old which I think is correct. My son is at the top of the 7 year growth chart and they were a bit big for him so I know he will be growing up in them in no time. According to the label, these shirts are made of 95% cotton and 5% elastane. but they feel like there's a lot more than 5% spandex in them. They are also much thicker and heavier than a regular cotton tank top. After the first wash the collar was a bit ruffled, almost disheveled, but I don't think this will be a problem as they are worn under a top layer. Overall, these jerseys look very high quality; much better than regular hanes cotton t-shirt or fruit print t-shirt. Only time will tell how well they hold up, but I think they're quickly becoming my son's favorite winter wardrobe. *I received this product for free in exchange for an honest and unbiased review.
