What the pros use

The ultimate advantage


Cool your core.

When you're hot, your body naturally cools off by emitting heat through the palms of your hands. RTX speeds up that process five times. Its slight vacuum pulls blood vessels to the surface of your palm. A cooling pad on your hand rapidly exchanges heat with an optimal cool temperature. In about three minutes, that coolness circulates from your palm through your entire core.
