[soup434]

I have seen a few posts regarding an underhood goggle warmer kit but i cant find any info on where to buy them or what machines they fit. Any ideas?
Thanks for your help:canada:

I've got a WPS bag under my hood. I know there are some other ones as well. Are there bags with actual heating elements in them, or are you relying on the heat of the engine to keep the goggles warm and dry?

What model of sled?

They also make heated riser bags that might be an option.
