The contour comes with the ability to mount by sticking a mount to your goggles
I prefer the 'rotating flat surface mount'. As the name describes this rotates to let you get the right angle then locks. I have one of either side of my goggles
(This is available seperately or as a part of mount packages)
i would always advise to also use the mini lanyard to attach to the goggles ensuring if it gets bashed hard that it won't fly off - I have have one sticky pad that didn't secure, but that was obviously not stuck as well as the rest I have done. I have seen people report loose fittings on all cameras, most of the time this is a matter of checking the sticky pad instructions, clean & prepare and then leave long enough before use
(Sticky pads are 3m pads)
