This is a super hat! It is very warm, and impervious to wind. I can see some people having issues with the sizing, but I wear 7 1/4 - 7 3/8 hat sizes, but the Large-Size in this hat seems to work perfect for me. It's a bit thick to get under a helmet, but it can work. The built-in ear flaps work very well, and it is great they are not tight fitting muffs, I don't how they work so well. I like the Olive/Black combination, but they don't seem to offer that anymore. I bought a spare one, because I would just be lost if I lost this hat. Best Winter hat (toque) I have ever owned.
