My girlfriend has gotten really into riding two up with me of late, but the winters in chicago can get to be a little severe with Highway travel. I have spent a small fortune on heated gear on myself years ago when I gave up cager life cold turkey, but I'm a little hesitant to buy new equipment when I'm not sure if it will get a whole lot of use. Basically, I was wondering if anyone has ever bought a heated throw blanket and wrapped it around their passengers inside jacket as a cheap heated liner? Blankets are around 30 dollars and I could always use the throw blanket at my house for reading on the deck on cool nights. Any experience or comments or suggestions?
