Pret Size Chart
Helmet sizes are based on the circumference of your head in centimeters. To determine the correct size, wrap a measuring tape around your head. Once you’ve determined the measurement, you can use the chart here as a guide.
Things to Remember: Generally, as helmets increase in price, they will include more venting, features, audio, use lighter materials, and offer more adjustability (BOA systems, adjustable sizing, etc.) to ensure proper fit.
M.I.P.S. brain protection system: Helmet liner and shell are separated by a low friction layer. This allows the helmet to slide relative to the head. This functionality reduces impact to the brain during angled impact, and is proven to reduce brain trauma.
A helmet is one of the most important pieces of gear you will buy. Buy a helmet you love so you'll always want to wear it.
