IMPORTANT NOTE: Double Helix is experiencing unforeseen manufacturing delays that are resulting in 6 month production lead times for all jackets. The Deviant Motorcycle Jacket from Japanese leather makers Double Helix is a modernized double rider asymmetrical motorcycle style jacket made from special tea-core horsehide leather. Double Helix opted for no epaulets or belt on this model, giving it a streamlined and easy-to-wear look. The Deviant is just as great on the bike as off, crafted from top-of-the-line horsehide leather in brown over-dyed black. This leather is highly sought after because of the unique way the black dye wears off to slowly reveal browns underneath. To hell with a perfect reproduction of jackets from days gone by, this is the stripped down, easy to wear leather jacket you've been dreaming about! Model is 5'10," 175 lbs wearing size 40/Medium.
