Description

A misted-up visor in cold or wet weather is the fastest way to lose sight of the road. This anti-fog insert fits behind the visor on your AGV and keeps it clear, so you can ride with the visor shut instead of cracked open.

Which helmets does this fit?

This anti-fog insert is matched to these models:

The helmet model name is printed inside the chin bar, under the lining or on the strap label. If yours isn’t listed, check the visor finder — visors are model-specific and a part from a neighbouring model usually won’t clip in.

How do I fit it?

Take the visor off, clean the inside with a dry cloth, peel the backing and press the insert on from one edge to the other so no air is trapped. No tools needed.

Shipping and returns

Free tracked shipping to the UK, USA, Canada, Australia and Europe. Delivery estimates are shown at checkout. If it’s not right, you have 30 days to send it back — see our returns policy.

    It fit my AGV helmet! There is a slight gap but if you push firmly it is fine!

    I attached it to a shield I bought from the same store and it installed easily. The shield itself has no recess for mounting the Pinlock, so I worried the Pinlock might interfere somewhere when opening and closing, but there was no problem.
