Aptly named, the Grivel Mutant is a lightweight mountaineering helmet with a modern, highly effective design.

Manufactured in an EPP construction with ABS reinforcement on the top, this model benefits from a combination of technologies allowing low weight with good all-round protection (on the top and sides). What's more, its innovative design features a top covered in symmetrical hexagons and a different pattern from left to right.

This headset adds a minimal adjustment system to reduce weight and allow compact storage.
