Giro Source MIPS Bike Helmet

The Source Mips helmet brings trail-ready durability and brain protection technology together in a design built for technical terrain and rowdy descents. Deep coverage meets aggressive cooling through 17 strategically placed vents and internal channeling that keeps air moving when you're pushing hard on steep climbs or navigating rocky singletrack. The Roc Loc 5 Mips fit system integrates brain protection directly into the adjustment mechanism for a secure, comfortable feel that doesn't compromise safety, while the full lower Hardbody shell construction stands up to trail debris and low-hanging branches. With a moto-inspired adjustable visor, CoolFit anti-microbial padding, and a lightweight 351-gram build, this helmet is equipped for backcountry adventures where protection and ventilation both matter.
