One coolant slips into the concealed pocket of each cooling glove, providing cooling impact to your palms. To cool your wrists, you can bypass the thumbhole and slide the glove up onto your wrist.

Such a small surface area, but such an important area for the transfer of temperature.

“Hand immersion is very good for whole body cooling because your hands have a lot of blood flow going to them, and you deliver a lot of heat to the hands when you get hot. If you put your hands into cold water you can lose as much heat through your hands as you would by wearing an ice vest".  (Professor Mike Tipton, Portsmouth University Extreme Environments Research Group)

THE SCIENCE OF PALM COOLING: The palms of your hands contain structures that are called AVA’s (arteriovenous anastomoses). These are a concentrated network of small arteries and veins which work like radiators or heat exchangers. This results in these areas being able to potentially exchange relatively larger amounts of heat or cold than their surface area alone would dictate. 

PALM COOLING FOR STRENGTH TRAINING: Cooling the palms has been shown to improve endurance when strength training (see this link in our drop-down menu). Because resistive exercise training is a mainstay of most competitive athletic programs -- and because there are few demonstrated gains outside of Performance Enhancing Drugs (PEDs) -- cooling your palms is a natural, risk-free training method.
