Bell Cage helmet advice

[jason90]

I noticed today that my helmet has 2 cracks in it, pic below

The cracks are on the front side of the helmet, where it sits on the forehead

Its just over a year old, and has not been dropped etc.



Has anyone else experienced anything like this ? Or any idea what has caused it

At a guess I would say it is sun mine looks ok will have a double check tonight ?
