I've had several Russell t-shirts over the years and they are by far the thinnest material. I've ever seen one in any of her shirts. I don't know why men's t-shirts are suddenly being made out of the thin fabric tissue paper. I bought some Russell t shirts a few years ago and they were made of a much heavier material. Maybe they are made specifically for Revain? They're still pretty well made and there's nothing wrong with these shirts, but I prefer a slimmer shirt. They are also a bit small for my taste. They call them "cotton shirts" but are they really a cotton/poly blend? If you're a fan of modern sheer t-shirts that are a little tight, then these are for you.
