I had Len’s fogging on the GoPro due to the temperature so will need to invest in a case so I can use silica gel packs during the winter, probably a good idea for extra weather protection as well. Otherwise camera worked well powered from the usb port in the fairing.
Thinking of one for this winter, the ride on Sunday and Monday was just on the edge, if I had ridden for more than 4 hours I would have really felt the cold. Has anyone here tried heated gilets?
