No, there's really no difference. All of these tanks are made of the same fabric, a cotton-polyester interlock knit which is a smooth knit with a good weight to it. Many of Blair's tops are made of this. It drapes well, doesn't cling, and it isn't see-through so you won't always have to wear a cami underneath, even with a white top. I have many of them and really like them. They are comfortable and fit well, and I think you'll like them. And so many colors to choose from!
