Smith Overtake Bike Helmet — A dome of honeycombed green “polymer cores” called Koroyd is the base of the Overtake helmet. Made for road biking, it’s marketed to absorb impact better than traditional foam in a crash. (Note: Smith released a similar mountain bike helmet last year.)
It’s lighter weight as well, weighing just 250g for a seriously ventilated, aerodynamic lid. Available this fall for $250.
