I'm trying to figure out how to keep my boots warm while sled skiing. I'm going to ride in snowboard boots with my ski liners in them, then put on my shells when it's time to ski. I need to figure out a cost effective way to keep my shells warm so I can put them on.
I have two ideas, first idea:
Dry bag lined with an old puffy or down blanket mounted/strapped to tunnel with a battery powered electric blanket inside.
Second idea: Same bag idea, but buying a pair of handlebar heating elements and wiring them to the bag. I'm not the most tech savvy so I'm not clear on how I'd do this.
I've seen some other ideas on this on other forums, but nothing really specific. Has anybody made their own heated boot bag?
