Ernest, ernest... Let's just post the two descriptions: Our Naked Cowhide Classic Racer Jacket has a bi-swing back, underarm footballs, adjustable stand-up collar and side buckles, zippered sleeves, polytwill lining with a zip-out pile liner. 26" back length. Made in U.S.A. Our Deluxe Heavy Steerhide Single Rider Jacket has bi-swing back, underarm footballs, adjustable stand-up collar and side tabs, and zip-out pile lining. Made in U.S.A. We suggest you order this style number one size larger. The first has side buckles, the second, side tabs (perhaps snap). The first also has zippered sleeves, the second appears not to have. Also, steerhide, and I am not an expert, I think is stiffer than cowhide. The Single rider jacket appears to be slimmer than the cowhide classic jacket. Tada, the magic of looking at text.
