Discover the Certified KOLL CS Fatbike Helmet

Blivet Sports proudly presents the KOLL CS helmet, now certified to meet the EN 1078 standard. Our KOLL CS helmet is the top choice for cycling and gliding sports enthusiasts, offering unmatched safety and style.

We have successfully passed rigorous testing, earning certifications for the CPSC safety standard for bicycle helmets (for ages 5 and up), the ASTM F2040 recreational snow sports safety standard, and the CE EN 1078 certification for bike helmets. These certifications validate the exceptional design of the KOLL CS.

The KOLL CS features a fully removable goggle retainer that securely holds ski goggles' wide straps in place. Transition effortlessly by replacing the retractable lens with your ski goggles for complete facial coverage. Blivet Sports' KOLL CS stands as one of the most comprehensive helmets on the market.

This helmet boasts lightweight and robust construction, utilizing premium materials and a unique design. Specifically crafted for winter use, it features a closed design to keep your head warm and includes a retractable (and replaceable) lens for facial protection. Experience exceptional comfort with its micro-adjustable stabilization system and a three-position neck adjustment system for superior comfort and stability.

The KOLL CS is available in two sizes: S/M (54 to 60cm) and the new L/XL (58 to 62cm), allowing you to wear it comfortably with our thin NASAK beanie.

When you choose the KOLL CS, you'll receive three lenses to adapt to various conditions:

• 1 x all-purpose clear lens
• 1 x tinted/blue mirror lens for sunny days and clear areas
• 1 x tinted/yellow lens to enhance relief

The KOLL CS helmet features strategic perforations, promoting air movement while preventing frost formation. This design maximizes visibility and shields your face and eyes from cold winds.

Note: The KOLL CS is an excellent choice for individuals who wear prescription glasses, as it accommodates most eyewear designs comfortably under the protective lens.
