The Mavic Deemax Trail Black Helmet is engineered to elevate your mountain biking experience by combining superior protection with unmatched comfort. Featuring advanced MIPS technology, it significantly reduces rotational forces during impacts, giving you the confidence to tackle even the most rugged trails. Its extended coverage protects critical areas around the temples and the back of your head, ensuring comprehensive safety without compromising on style or fit.
Designed with ventilation in mind, this helmet incorporates strategically placed external vents that channel air through large internal cooling pathways. Paired with CoolMax padding that effectively wicks away sweat and heat, it keeps you cool and comfortable throughout your ride. The ergonomic Ergo Hold SL+ retention system offers three adjustable positions, delivering a secure and personalized fit that stays in place no matter the terrain.
Beyond protection and comfort, the Deemax Trail Helmet boasts practical features tailored to mountain bikers’ needs. Its multiposition, protective visor enhances visibility and shields you from sun glare, while a mesh screen prevents insects from entering the front vents. A dedicated "sunglasses garage" conveniently stores your eyewear on the go, and compatibility with goggles makes it suitable for more downhill-focused riders. With certifications meeting CE-EN1078 and CPSC 1203 standards, this helmet is built to perform reliably on every trail.
Whether you’re navigating technical descents or exploring new paths, the Mavic Deemax Trail Black Helmet is the perfect companion to keep you safe, comfortable, and focused on the ride ahead.
