It's big enough that it fits without feeling like it's giving you a brain squeeze. Almost all of the other beanies i've tried or purchased are too tight for me. Not this one and it has style to boot. It's long enough that you can leave it bunched up on top or pull it all the way down over your ears with some room to spare. I have them in several colors. They sold out fast in 2009-get one before they're gone this year.
