Naked Cowhide Leather is the top grade of leather--only 5% of skins are graded as "Naked". The leather is soft and supple, with minimum flaws. This ultimate cowhide racer jacket features a zip-out lining that runs through the sleeves to help adapt to changing weather conditions, light reflector strips on front and back, two vents on the front and back, adjustable Velcro-closed straps at the sides for size adjustment, and cuffs with both zipper and snap close. Sized by chest measurement, 40 to 54. Measure around widest part of torso, wearing a shirt. Add 2" to exact measurement for correct size to order to give room for easy movement.
