Good beanie, not sure about under a helmet though

Got this for my wife to try as a helmet liner. She likes it but it's no good for under her helmet. The material is not the thinnest and the seems are prominent making it very uncomfortable under a helmet. Unless you have a lot of extra space in your helmet, I'd look elsewhere for a liner.
