1. Is the helmet safe?

FEND is designed to exceed US CPSC and European EN1078 bicycle safety standards. 

2. How does the helmet stay secure on the head? 

First, the helmet clicks into place to inform the user it is fully open. While the user is wearing the helmet, the adjustable chin straps keep it securely in place.

3. How do I know my size? 

Using a flexible measuring tape, wrap around your head just above your eyebrows. Our S/M size is 54cm-58cm and the L/XL is 58cm-62cm. For example, if your head measurement is 59cm, then you would choose L/XL. There is also an internal fit adjuster for added comfort. 

4. How much does the helmet reduce?

FEND folds down from 220mm to 110mm. Its overall dimensions when folded measure 110mm X 140mm X 290mm.

5. How is the helmet breathable?

FEND is designed with 6 streamlined vents to allow for maximum airflow to the head which will minimize overheating.
