OK. That’s a little colder than I was thinking. Just FYI for other Americans reading along…-20C = -4F. So I guess you do in fact probably need the battery operated shoe and glove liners. I was thinking that you’re in comparatively more moderate conditions like the balmy 30sF and 20sF where I am southern New England.
Maybe you could get a single battery that mounts on the water bottle cage that could feed those devices. But really…if you’re going to be in extremes like that…I don’t know if there’s much else you can do beyond the way you’ve been operating.
