Product Description
CoolMitt is a portable cooling system that uses your palm to rapidly lower your core body temperature from the inside out. Slide your hand into the mitt, and a circulating pump chills your blood at the surface of your palm before sending it back to your heart, cooling you from the inside in as little as 90 seconds. No ice bath, no cold plunge, no waiting around: just your hand and a few minutes.
Why it works
Your core temperature is one of the biggest limiters on performance. As your body heats up, it triggers built-in fail-safes that slow muscle activity and blunt output, which is exactly what CoolMitt is designed to counteract mid-session.
Your palms contain specialized blood vessels called arteriovenous anastomoses (AVAs) that are uniquely efficient at heat exchange, far more so than most skin surfaces on the body. CoolMitt takes advantage of this by circulating water at a precise 12°C against a cooling pad in the palm of the mitt. That specific number matters: it's calibrated to draw heat out efficiently while keeping blood vessels open, so cooled blood keeps circulating back to your heart and out to your muscles rather than getting restricted.
How to Use the CoolMitt
Between intervals: 2-3 minutes in the mitt between sets or efforts on the bike, treadmill, or in the gym. Ideal for indoor training where you can keep the device close at hand.
Post-workout recovery: 15-30 minutes after a hot session to bring your core temperature down and support faster recovery.
Before bed: A cooling session pre-sleep to help your body wind down and support deeper, more restorative rest, especially useful after a hot day or a late training session.
Setup
Fill the lower cooling reservoir with ice and water, fill the upper reservoir with water, connect the mitt hoses to the back of the device, power on, and slide your hand into the glove.
Keep your hand relatively still and maintain light, continuous pressure on the cooling pad for the best results. The device is battery-operated and holds a charge for several days of typical use, making it easy to bring along to the gym or on the road.

CoolMitt FAQ's
Everything you need to know before getting started.
It circulates precisely temperature-controlled water against your palm, where specialized blood vessels are especially efficient at heat exchange. This cools your blood at the surface before it returns to your heart and out to your muscles.
Temperatures that cold trigger vasoconstriction, which reduces blood flow and blocks the cooling effect you're after. CoolMitt is calibrated to a precise 12°C to cool effectively without that trade-off.
Between training intervals, for post-workout recovery, or before bed to support sleep quality — sessions typically range from 2 minutes (between efforts) to 30 minutes (recovery).
Yes — fill the two reservoirs, connect the mitt, power on, and go. It's battery-operated and holds a charge for several days of typical use.
