Protect your head!
I bought this for my girlfriend's visit, but her head turned out to be too large, so we will get her a new helmet in the future.
This one has not been dropped, it comes in the original packaging and with all the adjustments (see photos).

According to the box, it is designed for head circumferences between 20 - 20 7/8 inches or hat sizes between 6 3/8 and 7 1/4.

Feel free to stop by to see if you like the styling and if it fits you.

Considering how much you invest in your education, buying a helmet should be a no-brainer (pun intended).
