How Should Prevent Hybrid iMGs Be Properly Fitted to Athletes?

Follow these instructions carefully to properly fit Prevent's Hybrid iMG.

Please be aware that these instructions are specifically designed for Prevent's Hybrid (boil and bite) iMG and are not applicable to Prevent's Custom iMG. For instructions on adjusting Prevent's Custom iMG, please refer to this article.


Items needed:

  • Prevent Hybrid iMG
  • Boiling Water
  • Spoon (not metal)
  • Stopwatch/Timer
  • Cold Water

Prevent Hybrid iMG Fitting Process:

  1. Begin by bringing water to a boil using your preferred heating source.

  2. Carefully pour the freshly boiled water into a ceramic bowl. Immediately immerse the Hybrid iMG into the hot water and start your timer for 30 seconds without delay; it is crucial to maintain this timing for optimal results.

  3. After precisely 30 seconds, use a spoon to remove the Hybrid iMG from the water, shaking it gently for no more than 3 seconds to eliminate excess water. With both hands, grasp each side of the iMG to provide support to its frame, and then place it firmly in your mouth. Position the iMG over your teeth and bite down firmly for at least 30 seconds to ensure a proper fit.

  4. Once you have finished, remove the iMG from your mouth and submerge it in cold water for a minimum of 30 seconds; alternatively, rinsing it under cold water will also be effective.

  5. For optimal results, it is recommended to place the iMG in the refrigerator for 15 minutes. If refrigeration is not an option, allow the iMG to sit at room temperature for an hour before use.

Note: If you find that the fit is not secure after your initial fitting, allow the Hybrid iMG to cool for one hour before attempting to refit it using the steps outlined above.
