I too was looking for thinner spanex ones. I did not realize they were fleece. Too warm for now. Will use as it gets cooler out. They fit nice and are well made. I plan to buy more for Christmas gifts.
I bought it to cover my mouth and nose in public places due to the state regulation in COVID-19 pandemic. This neck gaiter does the job and is comfortable enough if you don't mind getting a little warm. You can tighten it on the top, too.
