Protect your head with a Coyle Wood Helmet. Yes, we said wood. Seems odd that the bike is one of the most sustainable vehicles, but green options for bike accessories don’t seem to exist. The Coyle may be the first of its kind. The Coyle Wood Helmet is made with salvaged maple, walnut, madrone, oak, and douglas fir that are sustainably harvested from live trees on a 15 year cycle. Instead of lining the inside with foam, Coyle chose cork harvested from Portugal. The helmets are 100% waterproof, and weigh roughly 21 ounces. Early test results show the natural wood fibers perform as good, and in some cases better than traditional synthetic materials. Support Coyle’s Indiegogo campaign here.
