By now, readers know I’m a firm believer in always riding helmeted- mostly because arguments against helmet laws are tremendously stupid. But what does one do when the weather turns cold? As it happens, a helmet is also better for shielding a rider’s face from cold wind blast than a tacky skull face bandana! The vents and visor of my Schuberth C3 Pro seal up nicely, the inner liner unfolds to cover vent inlet ports for additional protection and warmth, and the chin curtain encloses snug but comfortable around the rider’s neck to create an isolated environment. The one downside that’s always been with cold weather riders (or full face helmets stopped at a light) is fogging visors. There have been anti-fog sprays, coatings, etc. but most accounts I’ve read say they don’t work all that well.
Holy cow, this Pinlock insert works flawlessly. Seeing physics at work as the edges of my visor fog but the pinlock insert stays clear and provides visibility is just another reason to be grateful for science! My particular helmet has an easy and tool free removal/installation process, which made dropping in the pinlock even easier and faster than the YouTube video embedded in this post. But the most effective example I can show is this gif I stole from webBikeWorld.com. Read their review for more proof and testimonial of how well the Pinlock insert works.
Riding to and from work, I was so thrilled by how well it worked that I caught myself breathing as hard as I could in an attempt to overwhelm the insert. Despite my very best efforts to the contrary, the insert stayed clear. The worst visual artifact I’ve witnessed is a slight and only occasional prism effect at the edges of my vision – and even then it’s only caused by man-made lights when riding in the dark and could be a result of my LASIK. Applying the same care and cleanliness as when I homebrew some beer kept my optics fingerprint free, and has made me an avowed fan.
I won’t own another helmet without one.
