The other day the strap on my helmet snapped. It's not the main strap but the one that sits across the back of you head and has a tightening dial. So the helmet doesn't fall off but it also doesn't stay still anymore when moving my head around.
It's now effectivly useless as it rattles around on my head getting in the way and obstructing my view, etc. I'm considering fixing using gaffer tape (the old mountaineering adage that if you can't fix somehting using gaffer tape, you likely need to use more gaffer tape)?
Is this a good idea or should I discard it an get a new one?
Here's the model, it's a DMM brand:
The broken strap isn't quite visible on that photo.
Here's a similar helmet, see the plastic strap with the dial on it. That's what's broken. Notice it doesn't actually anchor anything in place, the main straps attach to the helmet itself:
