This hat is almost perfect. It has a really good balance keeping you warm around the ears but allowing the top of your head to vent a little and not overheat. Also it is a very good size, it doesn't sit on top of your head but at the same time it does not fall down over your eyes. The only complaint I have is the inner headband material. It is pretty loud as mentioned in several other reviews. Thankfully after wearing it for a few days it diminished and is pretty quiet now for the most part. Even with the crinkly headband it is my new go to beanie for all outdoor activities.
