Blanket for cold football games? Windproof?

[tripleshot]

DS plays football and baseball and I'm often freezing my ass off. I have poor circulation due to an autoimmune disease and it's hard for me to get and stay warm, especially outdoors when it's chilly/cold and windy.  I usually put hand warmers in my mittens.

I was was searching for a battery powered hearing blanket but I don't think they exist. I found some with a wind proof fabric on one side and fleece on the other. Any name brand recommendations?

I don't know of it's still sold, but we bought a Heated chair pad for a grandparent to take to football games.

I think I may end up getting the Mambe extreme blanket. I need to save up for it though. It's $139!

LL Bean has a fancy heated jacket. Pricey but hand warmers add up.

They sell heated clothes for motorcyclists. I don't know what it is right now, but there is a whole website for it.
