Here's an excerpt from the review:

"The D-pocket model according to Kevin is inspired by the biker's jacket of the 40s, but it's not a copy of any of the models of that time: completely zipped up it it looks like a double breasted cossack or ulhan miltiary jacket, and it's characterized by a very clean look thanks to the lack of studs Perfecto style, lack of epaluettes, slanted side pockets close by two horn buttons, and the D-panel. Most of the D-pockets based on the originals Schott 1928 and Buco J-23 are characterized by an angular beaty given by the squared shoulders and the oblique straight main zipped, this is not the case of the Pegasus whose style is dominated by curve lines: the main zipper is not straight but it's slightly bent, another gentle curve cut the lower part of the jacket covering the belt of the owner, the D pocket itself is mostly rounde with an oblique line parallel to the zipper and a point down which matches the point of the zippo pocket closed by another horn button. The angle of inclination on the central vertical line is equal for the main zipper and the D pocket zipper,creating a nice simmetry...
The back of the jacket is characterized by the three "by swing" panels that allows some mobility of the shoulders when riding (this is a motorcycle jacket after all), something taken from vintage german jackets, and the lower panel with the four belts to adjust the waist...
The horsehide used is a very nice chrome tanned mid weight leather, very flexible and elastic, with a shiny, almost wet finish. The shade of chocolate brown is very peculiar and difficult to catch with a camera, the grain of the panels perfectly matched...
The lining is a nice and soft cotton plaid, similar to tartan, very light but a little baggy. Globally, it's a mid season jacket, not too warm, but Pegasus also offers a herringbone wool lining...at least I think. The combination of this cotton plaid and brown horsehide made me choose the Pegasus and the jacket didn't make me regret my decision...
