Review on HiddenValor Boys Sleeve Round Neck Shirts: Premium Boys' Clothing for Underwear Essentials by Shane Schobinger

The tag says it's 100% cotton but it's a very thick stretchy material like lycra/spandex and doesn't feel like a nice soft cotton t at all shirt on. I kept them (probably out of laziness) but I expected them to be able to sleep in them. I'm sure they aren't very breathable so I don't know how much they can actually be worn. They also say not to tumble dry! I refuse to buy kids/teen t-shirts that can't be dried so we'll soon find out how they hold up because I'm washing them now. :)
