Troy Lee Designs D4 Carbon MIPS Bike Helmet

At only 1000 grams, the Troy Lee Designs D4 Carbon MIPS Bike Helmet is a featherweight dream. It barely registers as any extra weight on your head, remarkable when you consider its superior protection. Whether you're a BMX racer obsessing over grams or a jeans-wearing park rat who wears a helmet all weekend, you'll appreciate the protection-to-mass ratio of the D4. Not to mention how sick this thing looks!
