ProFx bands are designed to maximize performance and improve overall wellness. The ProFx wristbands are made of 100% medical grade silicone, treated with two exclusive charged ProFx discs, embedded with proprietary frequency technology. We are the original developers of the ProFx technology and design and manufacture our own bands. Each disc stores a large amount of readily available information, carefully formulated, to provide the body with the resources it needs for harmony and balance.
