Goggles query

[Benthompson96]

Evening all

Recently purchased the above PYRAMEX Goggles, now as an added preventative fog measure i ordered with the EXFOG unit as it says in the description they can be paired

I really cant see how this unit attaches to these goggles without doing some DIY (which im not apposed to)

Just wondering if patrol base have just had me on here or there is more to learn on the kit?

Thanks all
