In honor of Arbor Day, here’s a gorgeous bike helmet made out of wood. Yes, the Holz Bike Helmet by Coyle uses wood and cork to create an organic shell shell that naturally resists the effects of UV degradation and liner that absorbs impact really well. But in addition to being beautiful, these are serious helmets. Each helmet is reinforced with HMVK Polyurea impact shielding as well. You can also customize them with exotic woods if you’re not a fan of the standard Douglas Fir. You have to admit it: it almost like wearing a piece of art.
