To ensure a proper fit for your Troxel Sierra Helmet, take a tailor's measuring tape (the soft kind) and measure around your head above the ears and just above your eyebrows. If you have long hair, please measure wearing your hair as you usually do while riding. These helmets are adjustable to accommodate some variations. After measuring, please choose your size based on the chart below.

• Small - up to 22 inches or hat sizes up to 7
• Medium - 22 to 22 inches or hat sizes 7- 7
• Large - 23 1/8 inches and up or hat sizes 7 3/8 and up
