The Coolerz C420 Neck Shield uses an advanced evaporative cooling system with a water management system to maximize cooling, while minimizing moisture transfer to the wearer for:

• Enhanced cooling capacity
• Managed and directional evaporative cooling release
• Cools longer than other evaporative systems
• Reduces wetness to wearer
• Water repellent nylon inner
• Quilted nylon outer

Coolerz with Hyperkewl products utilize a unique polymer chemistry to achieve rapid absorption and stable water storage. The chemical formulation creates enhanced evaporation and longevity. Users can expect cooling fabric to provide temperatures that are up to 15 - 20 degrees (F) cooler than the ambient temperature. The exact temperature difference will depend on humidity, exposure to airflow, and environmental conditions.

Easy to use. Simply submerge in water for 1-2 minutes, then gently remove excess water.

Garments can be rehydrated as needed.
