A great product for the traveler that like to bike!

This is an excellent helmet for someone that likes to bike while traveling. I hate wearing the rental helmets and this foldable helmet makes it possible to bring your own without taking a lot of space in your luggage.
The helmet is lightweight and even though I have a large head it fits well.
