If you can’t see, then you can’t ride. I’ve always had trouble with goggles fogging up when using built-in breath boxes on most of my MX style helmets. I’ve used NO-FOG products almost exclusively to help me solve the fog problem. The soft neoprene mask fits around your chin, cheeks and nose, providing an extra layer of warmth and directing your breath down out the bottom of your helmet. Its form-fitting nosepiece fits snugly around the curves of your face to ensure a tight seal at the bottom of your goggles and keep out any of that moist air you breathe out. That provides crystal clear vision all day with maximum comfort and warmth. The NO-FOG mask is one piece of gear I can truly say I take on every single ride.
Cost: $54.99–$57.99
