XII WY Motorcycle Full Face Helmet Shield Insert - Photochromic Anti-Fog Film, Transitional Visor, Clear to Indigo Tint, Sun-Responsive, Transparent Indoors

Look at all that fog around the film; the anti fog works really well. It transitions to a dark bluish gray which was enough eye protection on a sunny day. Easy to apply as well with the guide template.

Pelicula antiempañante muy buena, el cambio de color a oscuro es muy rapido y en la noche se ve perfecto.

Photochromic doesn't work as you expect and even as it is on the picture in the listing. It does not become dark. It becomes a little foggy. The fogged visor is the last thing you need on the road.

It is great at anti-fog on my HJC i90 helmet. I could see the visor fogging up around it, but the film itself is perfectly clear. However, too much of the film's edge is in my field of view. I need it to be significantly longer (up to 14 inches to still fit in my visor), and 4 inches tall.

No es tan oscuro en la función transition pero es bueno lo reocmiendo

Ya lo he probado en condiciones de mucho frío y de lluvia desde leve hasta aguaceros muy fuertes y ha funcionado muy bien

Seems to keep fog away but in the dark I see 4 of everything. Very very bad for night and dark driving.

This works at keeping your visor from fogging excellently. It doesn't get darker though. It says photochromatic which made me believe it would darken in sunlight, but it doesn't. These pictures were taken after 20 minutes of direct sunlight. It does fit my Schubert C3 and is very clear and almost zero distortion. I really wanted the darkening and is why I went with this instead of the pinlock from factory. So far it appears to stop fog nearly as well, but I've only seen relatively warm mornings. It does fog briefly but clears almost instantly. If it darkened I would have given it 5 stars.
