hi, i'm new to sledding, just bought a new hjc cl-14 helmet, but it came with just regular cycle shield. will buying a breath box be enough to prevent fogging, or should i go with a electric shield? or do i have to buy both? or does a breathe box and double pane shield work? i was looking to buy a electric shield, thinking they are the best for fogging problems. any help would be appreciated. thanks.
