Focus on your riding without sacrificing style or safety. The Kooki Lady with Crystal Rivet is an ultralight riding helmet, suitable for any rider—even beginners—that combines design, safety, and comfort. It adapts to any type of attire, which, along with its lightness, makes it ideal for both competition and training.
This version of the Kooki Lady features the Crystal Rivet finish.
KASK conceived it with a universal design to meet the needs of all disciplines. Its structure is a double shell: a resistant lower shell made of EPS and thermoformed polycarbonate, combined with an upper shell made of injected ABS. The inner padding, made of hydrophilic fabric, is breathable and antibacterial and incorporates the integrated adjustment system. Front and rear ventilation promotes quick drying.
The four technologies of the Kooki Lady with Crystal Rivet
Integrated Airflow Control
Maximum ventilation via an air intake on the front of the helmet and a hot air outlet at the back.
Click-in System
The connection between the inner padding—removable and washable—and the shell is reinforced with three discreet pins that snap into the shell. This improves comfort and hygiene.
Synthetic leather chin strap
Hypoallergenic and easy to clean. Very comfortable, it helps prevent skin irritation.
Extra Sun Protection
The wide visor protects the skin from UV rays and rain without compromising visibility.
Safety and certifications
The Kooki Lady with Crystal Rivet is certified according to EN 1384:2023, the current European standard for riding helmets, and according to ASTM F1163 with SEI certification.
It also passes the WG11 rotational impact test, a KASK proprietary protocol verified by an independent laboratory that goes beyond the requirements of international standards. KASK publishes the CE declaration of conformity, information leaflet, user instructions, and packaging recycling guide for this model.

A helmet must fit firmly without pressing: it should not move when you lower your head or rotate when you shake it from side to side. If you are between two sizes, the rear wheel or adjustment system provides room within each size.
