LZRD X Mission Cooling Helmet Liner

Stay Cool Under Pressure.

The Cooling Helmet Liner delivers instant, long-lasting relief under your hard hat or helmet — no matter how intense the conditions. Just wet it, wring it out, and snap to activate powerful, chemical-free cooling that lasts up to 2 hours. Designed for athletes, workers, and anyone exposed to the heat, it cools up to 30° below average body temperature and fits comfortably under any helmet.

Lightweight, breathable, and UPF 50-rated for sun protection, it’s odor-resistant, machine washable, and built for performance — on the field, on the job, or wherever you’re pushing your limits.
