The Fox Speedframe Mips bike helmet is a versatile lightweight and comfortable helmet designed based on the knowledge of our professional MTB riders. The deeper profile of the helmet with an extended nape with double internal EPS padding provides an absolute level of protection for riding even in the most demanding terrain. MIPS™ technology was used in the shell to increase impact protection. * certification: CPSC, EN 1078, AS/NZS 2063 * weight for medium size: approx. 360 g * MIPS (Multi-Directional Impact Protection System) technology: in the event of an impact at an angle, the EPS shell of the helmet rotates a few millimeters along the MIPS layer, and thus protects the head and brain from a violent rotational jerk. Although this movement is only on the order of a few millimeters, the result is that MIPS significantly reduces the amount of rotational force that would otherwise be transmitted to the brain * The IN-MOLD® system is a technological process in which the shell and braces enclosed in the mold pressure injects EPS polystyrene foam. Their connection will reinforce the area of ventilation holes and ribs. The result is a compact, one-piece, light, safe and very durable helmet * structured internal construction of the helmet ensures perfect strength * strategically placed vents for maximum breathability and head temperature control * 3 frontal vents for absolute ventilation * removable, washable comfort pad that wicks away moisture * back wheel "retention" adjustable 360° Fit System for a perfect fit on the head * simple tightening under the neck thanks to the Y-strap system * visor compatible with MX goggles * spare linings in the package * deeper profile and increased protection of the back of the neck * sizes approx.: S (51 - 55 cm), M (55 - 59 cm), L (59 - 63 cm) * avoid exposure to aerosol sprays (insect sprays and sun creams), may cause peeling of the helmet finish * bicycle helmet * bicycle helmet, trial helmet * brand helmet Fox
