Mighty Grip is a heat activated thermoplastic powder. Sprinkle sparingly on your hands and press your palms together, as the powder warms up to your body , it will create a film of tackiness. The keyword here is heat. Students and instructors alike carry this product around religiously.
Those with warmer hands swear by this product. It also works for most pole finishes. It does not, however, stop you from sweating right through the grip aid, so Mighty Grip is great for adding tackiness to dry hands but not for combating sweaty palms.
