I have a large helmet by another maker but I needed a red one for my new red bike. I am girl with long hair and I don't think I have a big head. The helmet did fit but did not give comfortable room for a bandana and there was no space for my pony tail on the back, there is just not enough room and the straps on the back of the head only adjust to fit your head in, not to give room for a pony tail. Love the design and the color. Beautiful helmet, I am sad it didn't work for me.
