that suck, then they have their pro combat that are great. Pro combat costs a lot more, but it is really good. The Nike tee isn't great which is why you can get it for like $20, but a Nike Running tee or again Pro Combat are really good and cost $40. The problem is that it can be hard to distinguish and most people just want the cheapest gear without putting 2 and 2 together as to why it is cheap.
