How to measure your size
Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
In addition to the Tremor Helmet's cool style, it offers an easy to adjust fit system and 18 vents for breathability, making it a big hit with little shredders.
When Every Curb is a Jump and Every Patch of Dirt Screams for a Skid, The Tremor Helmet is There to Keep Smiles Wide.
Featuring some of the best technologies from our adult line, like In-Mold construction for reduced weight and enhanced durability, and our acclaimed Roc Loc Sport system for fast, secure fit adjustments, ensure that the Tremor is ready for any ride.
