Dont know if they make them that big, but I love my alpha burlys. I have the 1800 grams of thinsulate in mine. I can wear them in the early fall, all the way through the dead of winter. They are a little heavy, but very sturdy and warm. Had mine about four years now with just one pin prick hole from bared wire, easily fixed with shoe goo. Check em out they are an all around great boot.
