Cooling inserts for hats, hard hats, and helmets.
Chiller Body is a reusable, sealed phase-change cooling insert that fits inside headwear you already own. It activates at 65°F, stays dry on the outside, and gives workers, athletes, and outdoor users 20-30 minutes of targeted cooling per cycle.
Phase-change cooling
A fixed 65°F transition temperature gives controlled scalp cooling without ice-pack shock.
Works inside required headwear
Designed for the hat, hard hat, or helmet the user already needs to wear.
Dry, sealed construction
No dripping, no water activation, and no soaked hard-hat suspension.
Humidity independent
Cooling comes from direct contact, so humid conditions do not reduce performance the way they can with evaporative towels.
Choose the rotation that matches the day.
A 2-pack covers one person with a simple swap pattern. Larger packs are built for families, crews, teams, and event organizers that need multiple people cooled at once.
