Gorilla Cooling Shirts provide instant cooling relief when you need it most.

The polymer-embedded fabric works by quickly absorbing and storing water, and slowly releasing it over time through evaporation, reducing the effect of heat exhaustion and fatigue when used in combination with adequate hydration.
The inner and outer layers are made from polyester and can be comfortably worn on its own or over a t-shirt.

Features:

• Comfortable Polyester material.  
• Wear on its own or over a t-shirt. 
• Soak in cold water to activate cooling relief for up to 4 hours.
