COOLCORE® Arm Covers
Discover the secret behind COOLCORE: How it stays cold while you move (PDF)
Experience the next generation of cooling technology.
Unlike standard "cool-touch" fabrics that only provide a brief moment of coolness, HPI Arm Covers utilize COOLCORE®—a patented American technology that leverages evaporative cooling to keep you cold as long as moisture is present.
HPI imports this advanced material and handles all sewing and manufacturing right here in Japan (Made in Japan) to ensure the highest quality and fit.
The COOLCORE® Advantage: How it Works
Absorption: Draws sweat away from the skin into the fabric.
Wicking: Efficiently disperses moisture throughout the material.
Controlled Evaporation: Regulates the rate of evaporation to create a continuous cooling effect.
Chemical-Free & UV Protection: Provides health-conscious cooling with built-in UV resistance. No chemical additives used.
Superior Cooling: Proven to reduce surface temperatures by up to 10°C compared to standard materials.
Permanent Functionality: The cooling effect is physical, not chemical—it never washes out or degrades over time.
Why it’s Better than "Cool-Touch" (Contact Cold) Fabrics
Standard cool-touch fabrics rely on heat conductivity to steal heat from your skin momentarily.
Once the fabric warms up, the effect is gone.
COOLCORE® works through evaporation; as long as there is moisture (sweat or water) and airflow, the cooling persists.
Pro Tip: For maximum impact, use a cooling spray or wear these under a fan-equipped jacket. The increased airflow significantly boosts the evaporative cooling effect.
