"Helmet Hook"

[TriangleRider]

Thankfully, I've never dropped a helmet or had one slide off of a bike, so maybe I'm just lucky; "careful" eventually catches up to you, huh?

I never like just sitting my helmet on the seat or tank.
We stopped sitting our helmet on the ground years ago. While in Texas one of the locals told us not to do that because of scorpions.
We hang our helmets from a #2 Nite Ize S-Binder that's attached under the rear rack.

Fire ants here, but the idea is the same.  D loops fit around the rear luggage mount with no luggage.  If luggage is mounted, there is a nice ledge.  Yes, I've dropped my fair share of helmets.
