Frequently Asked Questions

Does it fit under a patrol cap or campaign cover?

Yes. The insert is thin and flexible, designed to sit flat against the crown of your head. It fits comfortably under patrol caps, campaign covers, baseball-style duty caps, and boonie hats without affecting the fit or professional appearance of the headwear.

Can firefighters use it under a fire helmet?

The insert works well under fire helmets for non-structural activities like wildland firefighting, overhaul, and standby duty. For interior structural firefighting, consult your department's SOPs regarding any items worn under NFPA-rated helmets. Many departments approve it for rehab and recovery between entries.

Is it suitable for extended outdoor crowd control or security details?

Absolutely. Officers on foot patrol, crowd control, or security details in direct sun benefit significantly from cranial cooling. Rotate inserts every 20-30 minutes using a cooler in the patrol vehicle or command post to maintain continuous cooling throughout a long detail.

How does the department procurement process typically work?

Many departments purchase through their existing uniform or safety equipment budget. We offer bulk pricing for department orders and can provide quotes formatted for government procurement. Contact us directly for volume pricing, PO processing, and any documentation your purchasing department requires.
