Frequently Asked Questions

Does it fit under a welding hood?

Yes. The insert sits flat against the crown of your head and fits under welding hoods, helmets, and skull caps without interfering with the hood's seal or adjustment. Many welders wear it under a welding beanie or do-rag for the most comfortable fit.

Will the insert be damaged by welding heat?

The insert is positioned on the top of your head, well away from the direct radiant heat of the weld arc. Normal welding does not generate enough conducted heat through a helmet or hood to damage the insert. However, do not place the insert directly on hot surfaces or near open flame.

How does it help with flash sweat during welding?

Welders face heat from two sources: the welding arc and ambient shop or outdoor temperature. The insert cools the cranial blood supply, which helps regulate overall body temperature and reduces the sudden onset of heavy sweating that disrupts visibility and grip.

Can it work alongside other PPE?

Absolutely. The insert is a thin, passive cooling element that layers under any headwear. It works with welding hoods, hard hats, bump caps, and safety glasses without interfering with fit, function, or safety certifications of your other PPE.
