“One of the cutting edge engineering projects that we have developed recently is HES (Homothetic Embedded Skeleton) construction technology,” explains Matteo Tenni, head of Bluegrass’ R&D department. “By partially embedding two shells into each other, we can reduce the weight of the helmet while increasing its safety factor. We are also offering designers new design opportunities.”
This promising technology has been used in the first All-mountain helmet designed by Bluegrass. And we have added in the highest standard of equipment.

EPS INTELLIGENT FUSION/ Different densities of material depending on the characteristics of each model.

HOMOTHETIQUE EMBEDDED SKELETON/ Spreads the pressure built up at the impact point, and thus dissipates the force of impact over the whole shell.


GRAVITY OCCIPITAL LOCK ADVANCED / Lighter with broader contact area, the pressure is distributed in a homogenous way.


EMBEDDED STRAPS ANCHORING POINTS/ The straps’ tensile stress is more evenly dissipated in case of impact.

KEVLAR STRAPS/ Ventilated, with breathability. Ultra-resistant.


THREE POINTS ATTACHMENT / Protects the face and especially the eyes from branches, sun, rain or mud flicked up.


FRONT PAD GEL O2 / Hypo-allergenic, anti-bacterial, made from thermo-stabilising polyurethane morpho-gel. Keeps the forehead cooler.


REMOVABLE ONBOARD-CAMERA SUPPORT / Leaves your helmet clean and tidy when not filming. Compatible multi-brand.

GOGGLE CLIP/ Keeps your goggle strap in place on the helmet
