Oh wow that sounds really cool!! That would be great for the chilly caves up here in the northeast!

Us motorcyclists have known about this for years though it does sound like this will be an improvement.

They even make them for divers these days though I've always been warm enough in a wetsuit so haven't needed to consider them.
Or just pack a couple of these

I remember really wanting battery powered electric socks back in the '70s. I think these are a little better!
