Focus on your ride without compromising on style or safety. The Kooki 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 features the Crystal Rivet finish.
KASK conceived it with a universal design to cover 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 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 with Crystal Rivet
Integrated Airflow Control
Maximum ventilation through an air intake at 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. 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 shields the skin from UV rays and rain without reducing visibility.
Safety and certifications
The Kooki 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 proprietary KASK protocol verified by an independent laboratory that goes beyond the requirements of international standards. For this model, KASK publishes the CE declaration of conformity, the information brochure, user instructions, and packaging recycling guide.

How to find your size

A helmet must fit firmly without pressing: it should not move when you tilt your head forward or turn from side to side. If you are between sizes, the rear dial or adjustment system provides flexibility within each size.
Frequently Asked Questions
Is it suitable for sanctioned competition?
It is certified according to EN 1384:2023, the current European standard for riding helmets, and according to ASTM F1163 with SEI certification.
