I've never felt a shirt this soft or light before. Good purchase! The texture is hard to describe because there's nothing I can really compare it to. "Silky" is the best way to describe it. It also does feel "cool", like the product listing says. It almost feels like there is a faint breeze when I'm wearing it.
The one thing I was wary of was wrinkles, because after a wash it looks all wrinkly. However after about 10 minutes of wear, the wrinkles disappear. Helps if you stretch it a bit too. Fits a bit loose for a M and I like that. ( I hate how other mediums fit tightly around my arms. My arms feel relaxed in this one. ) A good pajama shirt because it's way comfortable. All in all, would buy another.
