Frequently Asked Questions

How do I know if a helmet fits a round head?

A round head typically requires a helmet with a wider internal width. If you feel pressure on your temples, the helmet is likely too oval. Look for adjustable internal systems to fine-tune the fit.

Are skull caps necessary under helmets?

Skull caps are not mandatory, but they provide excellent moisture management. They keep sweat out of your eyes and protect your skin from abrasive padding.

Can I use a welding headgear on any helmet?

Not all headgear is universal. You must verify the hole alignment and compatibility with your specific welding hood. Always consult the manufacturer’s compatibility list.

How often should I replace my helmet?

Replace your helmet immediately after any significant impact. Even if it looks fine, the internal structure may be compromised. For daily use, consider replacing it every few years.

Is a heavier helmet safer?

Weight does not always equal safety. Modern materials provide high impact resistance without excessive bulk. A helmet that is too heavy can increase the risk of neck injury.
