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.

The Fend customer service team has been wonderful to deal with and address any issues I've had with this innovative product. Given it's the first of its kind that I know of on the market, I'm impressed by how the team is willing to adapt and provide support when there are issues.

This commuter helmet is perfect for those who need to store their helmet into a small backpack after use. It is durable, stylish, and shrinks to the perfect size. The incredible customer service was even able to provide me with spare clips and went above and beyond. I highly recommend Fend and its products!
