Another thoroughly positive surprise from the Land of the Rising Sun!

When helmet parts interfere with the image, who for other reasons can't cope with a goggle strap holder, as an enduro rider in demanding terrain does not want the dangerous Teletub tower on their helmet, or finds adhesive pads impractical but still needs an immersive FPV perspective, reach for either a chest harness or this chin strap holder.

The Chinese manufacturer K&F Concept actually doesn't promise too much with the reference to several years of development work and attention to detail on the small product insert. This is because the semi-hard Y-shaped base, lined with a rubber mat, is sensibly shaped, the four nylon straps are not firmly sewn - as is usual in the low-cost sector - but threaded through loops and can therefore be replaced or extended. The two quick-release fasteners with length adjustment snap in place and hold reliably - at least on my Airoh motocross helmet.

The two GoPro arms of different lengths with an extra 1/4 inch adapter (rubber disc is not included and must be manufactured by yourself if required) are robust and cleanly manufactured and should also fit cameras with an elongated form factor, such as the Sony X3000 or AS200V. The lock screws are easy to operate with gloves if you need to fine-tune the camera orientation while on the go. In addition, there are metal inserts everywhere, so no plastic threads break out.

And finally, the durable, robust mix of materials doesn't take offense when it gets really sweaty, dirty or wet. Easy to clean with detergent and hot water.

In my opinion, just under fifteen euros is a competitive prize - anyone who needs a removable mount for the chin rest of a full-face helmet takes it and I earn five points.
