Atomic Visor Ski Helmet Size Chart & Fit Guide

Choosing the right size for your Atomic visor ski helmet is essential for comfort, stability, and protection on the mountain. Atomic helmets use European sizing, with adjustable fit systems on select models to help fine-tune the fit.

At Stefan Kaelin, we've simplified the sizing information to help you select the right helmet with confidence.

How to Measure Your Head

1. Use a soft, flexible measuring tape.
2. Wrap it around your head, just above your ears and approximately 1–2 cm above your eyebrows.
3. Keep the tape level and comfortably snug without pulling it too tightly.
4. Record your head circumference in centimeters.
5. Compare your measurement with the Atomic size chart below.

Understanding the Atomic Fit System

Select Atomic visor ski helmets incorporate technologies designed to improve comfort and provide a secure, personalized fit.

360° Fit System

Atomic's 360° Fit System allows you to fine-tune the helmet's fit around your head. The adjustment mechanism helps achieve a secure, comfortable fit without excessive pressure.

Live Fit Technology

On models equipped with Live Fit, adaptive padding conforms to the shape of your head to improve comfort and help reduce pressure points.

Fit technologies vary by model, so check the individual product description for the features included with your helmet.

Atomic Helmet Fit Tips

Start with the Correct Size: Measure your head before ordering rather than relying on your size in another helmet brand.
Adjust the Fit System: If your helmet has an adjustable fit system, loosen it before putting the helmet on, then tighten it until the helmet feels secure without uncomfortable pressure.
Check Helmet Position: The helmet should sit level on your head, with its front edge just above your eyebrows.
Test the Visor: Raise and lower the visor to confirm smooth movement and a comfortable fit around your face.
Check for Movement: With the chin strap fastened, gently move your head to make sure the helmet stays securely positioned.
Check Eyewear Compatibility: If you wear prescription glasses, make sure the visor closes comfortably without pressing your glasses against your face.

Need Help Finding Your Size?

Atomic, CP, and Kask helmets use different sizing systems and fit characteristics. A size that fits comfortably in one brand may not be the right choice in another.
