Old MacDonald Helmet


Book a Demo


Ee-I-ee-I-oh! HardnutZ farm-themed helmet. We recommend you ask your local farmer for permission before cycling all over his fields.

This HardnutZ style is coverd in bug-eyed depictions of a range of much-loved farm animals. Lets see... there's a rabbit, a sheep, a cockerel, bull, a duck, a pig and a sheep of course, plus something that may or may not be a giraffe. Could be a goat.
