Café racer style jacket you've been looking for
Full-grain goatskin leather: more supple, smaller and finer texture than cowhide. Outside pockets - two chest, two hip - are zippered with chain pulls; no hardware on two inside pockets. Zippered sleeve cuffs do not have wind flaps, nor does the main zipper, compared to a similar but "proper" motorcycle jacket like the Schott 530. Like the 530, this jacket has shoulder gussets for mobility, but no underarm gussets for a sleeker look and slimmer fit; there are, however, two grommets in each underarm panel, open to the body lining, for ventilation. Split back panel with center seam like the 530, but with "faux belt" for an interesting mix in design language. Cotton body lining looks more like a light goldenrod color than what's shown; the polyester sleeve lining is black.
Sizing is accurate: I wear a 40R at 5'9" and 180 lbs, 16 neck, 42 chest, 34 waist, 34-35 sleeve, which puts me on the high-side of medium and low-side of large. Medium fits snugly but comfortably through the body and sleeves, as this style of jacket should. Length is perfect: cuffs hit above mid-hand with arms at side, hem hits near top of pant back pockets.
Doesn't have the heritage of a comparable Schott NYC jacket (the 530), but almost $500 less in price without cutting corners on craftsmanship. Beautiful jacket - you won't regret it.
