The invention of the Pinlock anti-fog insert was a major advance. Fitting to the inside of a crash helmet’s visor, this helps prevent the build-up of moisture on the inside of the visor in the form of misting or fog and hence, keep the rider’s vision as clear as possible.
The Pinlock works by absorbing moisture as well as insulating the inner surface from the cold outer visor, much like double glazing. However, Pinlock inserts aren’t available for every helmet and what can you do about a drop-down sun visor, many of which suffer from misting problems? What about glasses for spectacles-wearers inside a helmet?
You can generally help reduce or remove misting by opening a vent – usually the chin – or, in the worst-case scenario, the visor itself slightly. However, misting tends to be more common in damp or cold ambient conditions and hence when you probably least want to open the visor.
There are numerous proprietary products available to help prevent or disperse moisture forming on the inside of your visor (or indeed, glasses).
They generally seem to work by reducing the surface tension of the moisture so that instead of forming numerous tiny droplets, a single layer is formed which is transparent and, being close to the eyes, generally you can see ‘through’ it as you do with moisture on the outside.
Here is a selection of anti-fog products that are available now.
Hopefully this does what it says on the tin bottleu2026 Fog Gone is a natural product and, as a result, is safe for the eyes and the skin. Itu2019s applied to both sides of glasses though just the inside of a helmet and after a moment, polished dry. It comes in a 120ml bottle which is just right for keeping in your pocket or in your rucksack, along with visor cleaner.

Tucano Urbano Magic Spray
Magic might be a little strong but versatile is definitely appropriate for this spray from Italian brand Tucano Urbano. In addition to preventing fog build-up on visors, goggles and spectacles, it can also be used to clean the visor as well, making it very handy to keep under the seat of the bike. The flat-profile bottle is also handy and takes up minimal space.
Clean as well as anti-fog
Flat bottle handy
This handy little aluminium spray bottle contains 50ml of liquid that works at a molecular level, preventing the fluid droplets from forming on the surface. It wonu2019t work on anti-reflective coatings, as this prevents the nano-technology from working but itu2019s good for visors, goggles, spectacles and swimming or diving masks.
Suitable for various applications
Not for reflective lenses
This product from Muc-Off gets pretty good reviews online and Iu2019ve tried it and it definitely prevents the visor fogging up. Itu2019s supplied in a 32ml pump-spray bottle and you just spray it on and wipe it off with a tissue.
It’s good for visors, goggles, ski and snowboard goggles and lasts for up to five days. It also works on the outside of the goggles or visor to prevent water from sticking and helping it to bead off.
The Mist-Defy product appears very similar to the Tucano Urbano, with a flat, rectangular pump-spray bottle containing 15ml of product. The product itself is eco-friendly and a bottle should last for up to six weeks with individual applications lasting from 24 to 36 hours. You simply spray on and wipe off with a cloth and it will work on glass, plastic and all coatings on glasses, visors and goggles.
