These are the perfect little onesies for little ones in the spring, fall and for those cooler summer nights. I think they would be okay for the winter too, depending on where you live but they are like regular cotton material, not too thick but not thin eiter. I like the fit of them for my little one too; they are able to move around easily and comfortably while wearing these onesies. I recommend them and would purchase again!
