Certified Sweatsaver Helmet by Triple Eight

Ideal for biking, scootering, hoverboarding, and in-line and roller skating.   Comfort-minded with an adjustable fit, 2 different foam linings, and a plush Sweatsaver fabric.   Available in 2 sizes: S/M fits a head circumference of 12 to 22.5 in. (53 to 57 cm), and L/XL fits a head circumference of 22.5 to 23.5 in. (57 to 60 cm). For the most accurate measurement, use a string to measure the circumference of the head starting in the middle of your forehead. (If you’re measuring right in between these two sizes, we recommend choosing the larger one.)
