I could not find one big enough for my large noggin and mafia-like neck, so I had the GF make me one couple years ago out of Polar Fleece. About $2 bucks worth will make one, and I had her make a big flap on the front that I can tuck into my jacket like a bib. I also wear it snowmobiling, it's great. Also keeps the collars of jackets from grinding away at your neck when turning your head.
