Hello. I don't have a specific measurement for it, but it is not too thick. It fits great under helmets and hats and doesn't obstruct very much. But the soft wool is so warm and insulating.
I hope that this helps, but please let us know what questions you have and we'd be happy to help: 1-800-783-8326 or cyclewear@aerotechdesigns.com.
