What is COOLCORE®?
Developed using patented US technology, COOLCORE® is a revolutionary cooling material.
HPI imports this advanced fabric, ensuring every stitch and seam is Made in Japan for superior quality and durability.
The Cooling Mechanism (3-Step Process)
Absorption: Rapidly draws moisture (sweat) away from the skin into the fabric.
Diffusion: Spreads the moisture instantly across the entire surface.
Evaporation: Controls the rate of evaporation to generate a consistent cooling effect through heat of vaporization.
Key Features
Persistent Cooling: Unlike "Instant Cooling" (Contact Cooling) fabrics that only feel cold for a moment, COOLCORE® uses evaporation. As long as moisture is present, the cooling effect lasts indefinitely.
Up to 10°C Temperature Difference: Provides a surface temperature reduction of up to 10°C compared to other materials (*1).
Permanent Performance: The cooling function is semi-permanent and does not degrade, even after repeated washing.
Chemical-Free & UV Protection: Formulated without any chemical additives for a skin-friendly, healthy experience.
Superior Comfort: Keeps you dry and comfortable without stickiness or stuffiness.

Best Ways to Wear
Optimized for use as industrial or heavy-duty innerwear:
With Fan-Cooled Jackets: External airflow accelerates evaporation, drastically increasing the cooling effect.
With Cooling Sprays: Can be combined with over-the-counter cooling sprays for maximum impact.
