Lockable Heritage Bike Helmet

Stay safe in the bike lane with this lightweight, vintage design-inspired helmet. It has a Secret Poplock so you can attach the helmet to your bike with your lock — no need to take it with you once you're on foot. The one-handed magnetic fastener on the nylon straps also makes it easy to buckle up on the go without taking your hands off of the handlebars. And, the low-profile visor and seven vents make hot, sunny days a breeze.
