When designing the Smith Convoy, we set out to create a mountain bike helmet that felt like it was tailor-made for your head. An adjustable dial on the back lets you fine-tune the fit for comfort. When it comes to comfort and protection, the helmet ticks all the boxes. It has a Mipsliner system and all the ventilation you'll need through the hottest days on the trail. In addition to easy integration with performance eyewear, it also features outside channels that store your shades when dusk sets in.
