Just tried on my new Beanie. I have a small head and it fits tight, which I like, and it will probably stretch over time like my previous ones. Although its advertised to fit over your ears when cold, which it does, if you don't need it to cover your ears there is a pile of material on top of your head. It looks a little "dorky" and may interfere with helmet fit and comfort. I will find out after a few rides. I took off a point for this.

I got the carbon color beanie, which is dark gray. I misplaced my last black one, so this should be a bit easier to see if misplaced. So far I've used 3 beanies for cooler weather, mainly biking, or under a ball cap to keep my ears warm. This is the best one because:
- It's larger (longer?) than needed, which means I can pull it way down over my ears to keep cold wind out.
- It fits snugly, and prevents wind from blowing under it to my ears.
- It's not overly thick, which means it works well under a bike helmet or a ball cap.

I haven't had it long enough to find out if it is warm enough for sub-freezing days, but then I didn't buy it for the dead of winter. I'm happy with the beanie and would buy it again.

Perfect for running in cool weather. I have several of them.

i work outside in Florida its hot and sweaty these beanies are just what i need!!!! 5 stars
