Run cool under the sun
Average temperature drop versus traditional EPS foam helmets — measured in identical climate conditions.
Heat Stress Engineering
Built to keep your crew 11 Degrees Cooler
Heat doesn’t just feel uncomfortable — it costs you hours, focus, and money.
Caco America’s Performance Safety Helmets run an average of 10.92 °F cooler than traditional EPS-foam helmets, engineered with Koroyd® cross-ventilation to keep field crews sharp, safe and on schedule.

The Science of Cool
Koroyd®. Not EPS foam. Engineered tubes that breathe.
Where EPS foam densifies and traps heat, Koroyd is 95% air — a welded matrix of micro-tubes that vents heat continuously while absorbing impact at a constant rate. Same shell. Radically different physics.
-
01
Better impact absorption. Koroyd outperforms EPS in both direct and oblique impact tests by absorbing up to 78% of material thickness constantly — versus 60% in EPS, resulting in 48% less energy transferred to the head.
-
02
Continuous cross-ventilation. Open-cell tube geometry channels hot air away from the scalp instead of insulating it against the head, and enables cool air from the outside to vent in.
-
03
Washable, hygienic core, no odor. All Koroyd and no metal components, enables the helmet to be completely washable.
-
04
Visible end-of-life indicator. Koroyd crushes visibly on impact — no guesswork about whether a helmet should be retired from the field.
Why crews trust them
Cooler, lighter, safer — measurably.
Every spec on this page is independently tested. No marketing softening. The numbers that follow are the difference between a crew finishing the shift fresh and a crew slowing down by 3:00 PM.
48% less energy transferred from the impact
Engineered for the unexpected
Koroyd® absorbs energy at a constant rate across its tubular structure — including angled impacts EPS struggles with.
95% air
Designed to breathe
The Koroyd core is 95% air. Hot air rises out instead of being trapped against the scalp like in EPS foam.

Crumple. Absorb. Protect.
Koroyd® is an advanced impact technology built from welded tubes. On impact, the tubes crumple instead of springing back — absorbing energy through sacrificial plastic deformation rather than transferring it to the head. The same open-cell architecture that absorbs energy also lets hot air vent freely, so protection and breathability are engineered together.

Welded tube structure
An engineered core of welded tubes, built to perform in the toughest environments.
-
Crumple. Absorb. Protect.
On impact, the tubes crumple on a constant rate in difference to the eps foam and use up to 78% of its material to absorb the impact vs the eps foam that only uses 60%.
-
Direct and angled impact protection
Instead of springing back like traditional foams — helps reduce both direct acceleration and the rotational motion linked to head injury.
-
Advanced breathability
Open-cell architecture lets hot air escape from the wearer’s head by letting cool air in across the full surface of the core, delivering ventilation without compromising protection.
