Designed for the modern mountain biker who demands performance without compromise, this helmet delivers a superior blend of safety, comfort, and style, ensuring you can push your limits with complete confidence on any terrain.The core of its protective capability lies in the integration of the Smartshock® Rotational Protection. Featuring the 100%® ALTEC's patented Smartshock® elastomers, this advanced system is engineered to begin defusing rotational crash energy immediately upon impact. This intelligent design provides an essential layer of protection against the complex forces common in real-world mountain biking accidents, giving you the peace of mind to ride aggressively and explore new lines.Stay cool and focused, no matter how intense the ride gets. The ALTEC is engineered for massive airflow, with an impressive 15 ventilation ports that work in unison to draw in cool air and exhaust heat. This exceptional ventilation system helps regulate your temperature during strenuous climbs and long, sun-exposed descents. Despite its expanded rear coverage for enhanced protection, the helmet maintains an impressively lightweight feel, ensuring all-day comfort without ever feeling cumbersome.Functionality is at the forefront of the ALTEC's design. A multi-point adjustable visor provides a wide field of view and can be easily positioned to shield you from sun and debris, or pushed up to accommodate goggle stowage during transitions. For riders who prefer sunglasses, an integrated storage system securely holds your eyewear when not in use. The fit is fully customizable thanks to an adjustable ratcheting system for precise, single-handed adjustments. This is complemented by a washable, moisture-wicking anti-microbial liner that keeps you fresh ride after ride. New for this model, the Fidlock SNAP magnetic buckle allows for effortless and secure fastening, even with gloves on.Technical Specifications* Construction: Multi-Density EPS foam injection molded with polycarbonate in size-specific molds* Eyewear Integration: Integrated sunglass storage system* Fit System: Adjustable ratcheting fitment system* Certifications: CPSC, CEAttributes* Adult, No TechnologyIn The Box* Extra comfort-liner for customized fitment
