How Do You Determine Your Helmet Size?

What if you’re in between sizes?If you’re in between two sizes we recommend heading toyour local Smith retailerso you can try on the sizes in person and find the perfect fit.
Final adjustments: Once you’ve determined your size and ordered your new bike helmet, there are a couple of final adjustments to make so that it fits you properly. Use the adjustment dial at the back of the helmet to fine-tune the fit of your helmet. Your helmet should feel snug but not tight and should stay put if you shake your head up and down and back and forth. Next, buckle the chin strap, and adjust it so that if you open your mouth wide, your helmet presses slightly into the top of your head. You should be able to fit two fingers between the buckled helmet chin strap and your chin.
