Bern Bike Helmets

Freed from basement storage lockers and freshly oiled at neighborhood repair shops, bicycles are emerging from winter dormancy. Also coming out of those storage lockers: dusty bicycle helmets. Like bikes themselves, helmets have become more efficient and stylish lately. Duxbury-based Bern is making them thinner and lighter while increasing their strength. And color options? Let’s just say there is now a bright purple helmet to complement the white Italian racing bike you’ve been itching to ride. $80 at Cambridge Bicycle, 259 Massachusetts Ave., Cambridge, 617-876-6555,
