Features:

When the temperature rises and you're still on the job or in the game, you need more than a breathable hat — you need active cooling. Instant Cooling Skull Caps use dual-layer cooling technology that activates on contact with water. In just 3 steps (soak → wring → shake), your cap stays cool for hours. Re-wet anytime to reactivate — no batteries, no chemicals, just instant relief.
The 3D mesh breathable construction provides UV sun protection and moisture-wicking performance, keeping your head shielded and dry whether you're on a construction site, cycling trail, baseball field, or gym floor. The ultimate hat for men and women tackling heat all summer long.
Stay cool with our adaptable, one-size-fits-most caps. Instantly activated cooling and reusable design for various uses.
