KOLL GEN 2 — The Evolution of a Classic by Blivet Sports
First introduced in 2018, the KOLL was one of Blivet Sports’ most iconic early products. Exceptional from the start, it now returns in a fully reimagined form: the KOLL GEN.2 — more versatile, refined, and powerful than ever.
Specifically designed for fatbiking, the KOLL GEN.2 remains the most complete helmet in its class. Lightweight, durable, and built with premium materials, it combines protection, comfort, and intelligent design. With its new 8-vent configuration, it now performs seamlessly in both winter and summer conditions.
The helmet’s profile has been completely reshaped — sharper lines, clean finishes, and a thoughtful integration of new technical features. The result: a distinctive, bold, and functional design that sets a new standard in both quality and aesthetics.
The KOLL GEN.2 features 8 ventilation openings positioned at the front, back, and top. The 4 top vents are manually adjustable using a sliding mechanism, allowing you to regulate airflow based on effort and temperature. And for colder rides, the removable ear covers provide optimal protection and customizable comfort.
A must-have feature, the retractable lenses on the KOLL GEN.2 deliver excellent protection against wind, cold, branches, and debris. They are 100% retrofittable with previous KOLL helmets and feature perforations that prevent fog or frost buildup — ensuring clear visibility at all times. Compatible with most prescription glasses, the lenses fit perfectly over your eyewear.
Including:
Equipped with a micro-adjustable stabilizing system and a 3-position rear adjustment mechanism, the KOLL GEN.2 provides a secure, personalized fit. It’s double certified under both the North American CPSC and European EN 1078 standards, guaranteeing the highest level of safety. Available in two sizes, it is fully compatible with Blivet’s lightweight NASAK beanies.
