Finding and fitting a helmet for your constantly growing 5 to 10 year old racer just got simpler. The mini vapor and the mini champ youth helmet with our Quick Fit Inserts (QFI), is designed ‘to grow’ with your young racer all the way to adult size. The Quick-Fit memory foam sizing pads (included) makes fitting and refitting the mini vapor or mini champ fast and easy. A single mini vapor/mini champ helmet fits youth sizes small, medium, & large. You can even custom shape the inserts for hard-to-fit or in between sizes. (A single mini vapor and mini champ will fit youth sizes: small, medium & large with included Quick Fit Inserts). The mini vapor and mini champ youth helmets are SFI 24.1 approved (youth helmet standard) for QMA/WKA/NHRA/IKF use. Featuring ‘Ripple Effect’ boundary layer aerodynamic features incorporated in the shell construction and interchangeable cheekpads for a custom fit.
