    So soft and comfortable

    I love the feel of it. I normally end up taking my nightie off because I’m too hot even in the winter. Not the case with this. I probably could have bought a medium.

    Will be buying more in the future!

    At last, a shirt that keeps me cool on winter nights

    I have struggled for years to stay cool on winter nights— although I go to sleep in a cool room under a light quilt I usually wake in the middle of the night over heated. This sleep shirt has worked well to keep me cool enough, but also warm enough. It’s expensive, but a full night’s sleep is worth it.
