Helmets are an absolute requirement, and required by law in some areas. Choose a helmet that has styling that appeals to you. Brighter colors are nice since they are cooler in the sun and increase visibility to other road and trail users.
Features
Components of the Helmet
Vents improve cooling by allowing air to flow through the helmet
Retention System adjusts fit with a slide adjustment or dial.
Removable Pads absorb sweat and cushion for a comfortable fit. Periodically remove the pads and wash them to remove salt build up and prevent odor.
Optional Visor included on some models shades the eyes and can protect against mud or rocks kicked up from the rider ahead.
Sizing & Fit
Most of today's helmets have an adjustable sizing mechanism that allows quick and easy changes to the helmet's headband.
How to Properly Fit a Helmet:
Open the sizing band (A) all the way.
Place the helmet level on your head (B). Slowly tighten the headband (A) until it is snug but comfortable.
Adjust the straps so they meet just below your ear(C).
Once the side straps are adjusted properly, tighten the chin strap (D) to be comfortably snug.
When finished the helmet should move no more than 1 inch in any direction and be impossible to remove from your head without unbuckling the strap.
