The Altitude are the iconic aviator style sunglasses. This style looks great on just about everybody. The Wood Worn Altitudes are a confident look with a little bit of "bad boy" (or girl) thrown in. You may be wearing these while riding your motorcycle or while riding the subway to that business merger. The Altitude in Black Walnut carries the iconic look to the next level. The subtle, dark brown, wide wood grain is bound to make these an instant classic. They are made of 5 crossgrain layers of Black Walnut hardwood, which makes them strong and sturdy, just like your resolve. The Altitude feature smooth lines and maximum lens surface, and come standard with stainless spring hinges so they can accommodate small to large faces. If you couple that with the fact that Wood Worn wooden sunglasses weigh on average over 30% less than their traditional plastic or metal counter parts, then you have shades you can happily wear all day long. And let's not forget the Polarized lenses, rated at UV400 which block out 100% of all harmful UVA and UVB rays, that also come standard with all Wood Worn sunglasses. Finished with a scratch resistant coating and highly impact resistant, these lenses are made to live in.
