I just got this cap and was able to use it only a couple of times, but the reasons I bought it are: that it is machine washable, that it keeps my head warm (nicely insulated), protects my ears from the cold and sun, and the company name stands for quality. I wore it on a couple of runs and it does all it claims. It keeps my head/ears protected and warm, it protects my eyes from the sun. I love that it is machine washable, because after a few uses, it will need it. Don't know how it will hold up, but I expect it will do fine. It is nicely insulated and the chin strap is a great idea for windy days when a cap can easily fly away. The only concern is, and this would be for any hat that covered the ears, hearing my surroundings gets thrown off a bit. It's an adjustment, but I am glad that I got it for it does all that it says so far.
