The laws for skateboarding helmets vary from state to state. Many states require that skaters wear a helmet under a certain age, and some states like California make all skaters under 18 wear a CPSC Certified helmet at all times. CSPC skateboard helmets usually have an EPS protective liner that meets the safety standards for skateboarding. Make sure you check your state's regulations before ordering.

CPSC Certified Helmets: California requires that all skateboard helmets must meet the requirements of the United States Consumer Product Safety Commission (CPSC). Section 890.4 of the Streets and Highways Code enforces these standards in California and will not allow Warehouse Skateboards to ship non-CPSC Certified helmets to California.

Most bearings are measured by an ABEC rating. The higher the ABEC rating, the more accurate and precise the bearing will be. This rating system includes grades 1,3,5,7 and 9. The closer you get to an ABEC 9 rating, the faster and less friction you will have when skateboarding.

Many companies do not use the ABEC rating scale. They brand their own specific technology.

Note: Each brands skateboard helmet size will vary; therefore, it is best to measure your head and refer to the sizing chart specific to each brand of helmet. In order to properly measure your head, follow these steps:

Wrap a soft tape measure around your forehead, just above your eyebrows and ears. Keep the tape measure level from the front to the back of your head. Your skateboard helmet should sit low on your forehead.

If you do not have a flexible tape measure, try marking a string and measuring it against a ruler.

If the helmet is a gift or you cannot measure the skater's head, measure the inside of a current helmet or hat they wear.

Within each skateboard helmet product page there are specific measurements for each skate brand. Use that information, along with your head size, to determine your correct helmet size before placing your order. This will ensure that you receive the best fit.
