Looking to hear from those of you who know of specific MTB helmets (particularly non-full face) that are compatible with mounting a Go Pro camera under the visor of the helmet?
I currently use a Fox Dropframe for trail riding and I’ve found that this is not a very Go Pro mount friendly helmet.
Most non full face mtb helmets usually have a flat 'camera mount' space on top so there are plenty to choose from.
Most peaked helmets (including your Fox Dropframe) will be able to fix a sticky pad Go Pro mount under the visor. The only difference is whether the peak can be adjusted high enough to allow the Go Pro not to obscure your vision.
Here is a generic one that mounts under the visor (for your specific helmet apparently) but read the disclaimer you could end up head butting a low hanging branch because as far as I know the Fox Dropframe's visor is fixed and can't be adjusted.
