I bought a larger size than I'd normally get based on the reviews that they shrink. So when they shrank in the drier, I was not surprised nor upset, and now they fit right.
But they are not soft at all. They feel rough and itchy all over my legs (and you can tell that the quality is poor even at first touch) making it very uncomfortable to sleep in them. They feel almost the same as poor quality wool.
This surprised me because before purchasing I checked the material, and the reported composition is exactly the same as some tanks (of another brand) that I use almost daily. Those tanks, however, feel very soft and I often use them to sleep.
So overall I am disappointed. Not worth returning, given that they were cheap, but I would not recommend to anyone.
