One of the highest-performing youth MX helmets on the market, the LS2 Gate Youth full-face motocross helmet offers technology and features rivaling helmets that sell for twice the price. This is an amazing lid and the youth model is exactly the same as the adult, only smaller. Let’ start with the shell. LS2 uses their proprietary Kinetic Polymer Alloy (KPA) for the shell. It’s lightweight, offers just a little flex as part of the energy management system, and is ultra-strong. It tests as well as the best composite materials in the world and is the perfect material for a racing helmet. This proprietary material uses nanotechnology to blend microscopic particles of aramid fibers into a high-end polymer. This material is absolute state-of-the-art in energy management materials, offering a bit of built-in flexibility to disperse energy, the penetration resistance of high-end fiber products, and a lightweight shell. Moms will love the removable, washable interior comfort padding, allowing you to keep the helmet as fresh as the day it was new. It uses a high-tech fabric that wicks moisture, dries quickly and keep your young pilot cooler and more comfortable. The Gate Youth utilizes LS2’s Emergency Release System, always there if you ever need it. Our comfort pads are pre-curved using LS2’s 3D laser technology for all-day comfort and no hot spots. Multiple intake and exhaust ports are ported through the internal EPS to allow flow-through ventilation. The cheek pads are slightly curved to accommodate eyeglasses. An ECE 22.05 rating is accepted for racing by most sanctioning bodies in the U.S. This is a high-performance helmet. It just happens to be reasonably priced. LONG-OVAL FIT. Meets or exceeds both DOT FMVSS 218 and ECE 22.05 certification.

How to measure
Measure the circumference of your head with a tape measure, starting above the ear, circling completely around about half an inch above the eyebrows and across the fullest part of the back of the head. Measure several times for accuracy. If you fall between two sizes, choose the larger; the helmet should be as snug as possible without causing pain.
