It is very thin. It does cover so it is not see through when wearing. I held it up and with the front and back layers together I could still see through it. It seems this is the trend with t-shirts. All the new ones I bought have this problem except for The Mountain brand but they aren't plain. I bought these to wear around the house while cleaning. They would be cool in the summer. I am a swoman and they fit me well. They don't seem to shrink so far. I have only washed them about 3 times. That is why I bought the blend. The color is exactly like the photo. I will buy more.
