Giro Ethos MIPS Helmet Choose to ride. Choose to be seen. The Giro Ethos MIPS is a revolution in everyday transportation - a compact, stylish commuter helmet with integrated LED lights and handlebar-activated amber turn signals built in. Two front white lights and two rear red lights are USB-C rechargeable and run for up to 10 hours in low-blink mode, while the intuitive handlebar remote controls light modes, brightness, and turn signals without taking your hands off the bars. A TPU soft rubber waterproof brim, full Hardbody(TM) coverage, and the Roc Loc(R) City MIPS fit system with quick-dry padding keep comfort and durability sorted, while Mips(R) Brain Protection System adds rotational impact protection for peace of mind on the daily commute. Whether you're a dedicated urban cyclist, running the kids to school on an e-cargo bike, or simply want to be visible on the road - the Ethos MIPS is what riding smart looks like.
