"This product has a MIPS rating, which helps to prevent concussions. I think it’s a must for children on bikes, scooters, skateboards, and skates to prevent serious brain injury when they fall and the extra cost is well worth it. My grandson also loves the designs this brand offers, which also makes it fun for him to wear!."

Determining Your Helmet Size

The proper helmet fit is one of the most important factors for safety and comfort. A snug, aligned fit will achieve a safe and secure ride. Below are 3 simple steps to determine the proper helmet size.

Step 1





Measure the circumference of your head with a tape measure – roughly 2.5cm above your eyebrows.

Take several measurements to make sure you have the largest size.

If you do not have a tape measure, use string or a phone charger cable and measure it against a ruler.

Step 2





Once you have determined your helmet size, try it on. The helmet should be worn level on the head, and hot slide or move freely when you roll your head form side to side. 

If this is the case, you have a helmet that is too large. Extra padding may help provide a better, more snug fit.

Step 3





Be sure the front of the helmet lays just above your eyebrows and that the back of the helmet does not touch the nape of the neck.

The chin strap should fit snug to where you can only insert 2 fingers. If thee skin on your forehead moves slightly, you have a good fit.

What is MIPS?

*MIPS is a low-friction layer that sits between your baby’s brain and the helmet. The liner would slide 5 to 15mm in all directions if there were an impact, reducing damaging forces to the brain.
