This unique product finally answers the question: how to leave your helmet with your bike without it getting wet, damaged or stolen?
The helmet remains completely protected from the elements at all times. However, the chain and lock (not provided) is threaded down a waterproof tube which runs through the shield aperture and out of the bottom of the helmet (see image) so that you can lock it to the bike. The easiest lock to use is an armored cable lock (such as an Oxford Tripwire), but you could equally use a chain lock or a regular cable lock.
Secure way to leave your helmet with your bike, and keep it protected from the weather.
Suitable for chains and cable locks.
Handy Velcro brand hook-and-loop hanging strap to keep your helmet off the wet ground.
Fits chains and cable locks up to 1.6" (40 mm) in diameter.
Note: Chain and lock NOT included, must be purchased separately.
