I cant remember the brand but I have one i bought at "Hot Leathers" last spring. Its fleace up to the chin, then thin cotton over the top.With a full face helmet it works great.
The coldest air temp I've used it in was 35F..my hands and feet froze but neck and face where fine.
Price was about 15 bucks.
Oh the down side looks like you have a condom on your head when you take the helmet off.
