When designing the Smith Convoy Mips Helmet Smith set out to create a mountain bike helmet that felt like it was tailor-made for your head, hit all the high notes in venting and MIPS® Brain Protection, and was specifically designed with the features mountain bikers are looking for. With a turn the dial at the back of the helmet the VaporFit™ system adjusts like a halo around the skull, for a perfect to you fit. This has a MIPS® liner system that reduces rotational forces caused by angled impacts to the head, lightweight in-mold construction, and an integrated visor that works with goggles or shades. The AirEvac™ ventilation system integrates with Smith eyewear, causing a constant pull of air behind the lenses for fog-free lenses even when you’re working in heat. Rounding out the features, a performance comfort lining that wicks and dries quickly, and nifty outside channels that store your glasses when your day extends further into dusk than you expected it to.
