The Bell Youth Sidetrack MIPS Helmet brings together all the bells and whistles you need to keep your little adventurer's noggin safe when they're out on two wheels. With mountain bike helmet inspired design, cooling ventilation, and industry leading Multi Directional Impact Protection System MIPS safety, this helmet is comfy to wear and packs a huge dose of safety into an effortlessly cool package. The big draw with MIPS is its ability to reduce impact force and decrease concussion risk in the event of a crash. MIPS consists primarily of a strategically anchored liner on the inside of the helmet that looks simple, but serves a rather complex purpose. That little liner is designed to move independently of the helmet shell to effectively redirect impacts and reduce force on the brain compared to standard, non MIPS helmets. If your kid does happen to crash, MIPS technology reduces the risk of concussion and dramatically increases the chances of walking away without a head injury. Bell incorporates its ErgoDial Fit System, which makes for an easily customizable fit, and a snap in visor that adds in some style points while keeping eyes protected from direct sun and drizzle. The Sidetrack MIPS also provides extended coverage at the back of the helmet.
