This was a prototype of the "Movement" leather jacket from Collateral Concepts made when testing out different leathers for final production use. I'll let the designer / maker himself describe it from his original posting on SZ: "Guidi Calf leather with two way locking custom cut antique silver tone heavy duty locking RiRi zippers and fully lined in organic pure black American cotton. The body is constructed of a front, side and back panels that allow contouring through the sides for an anatomic fit even better than before. The front curving seam has a fully lined and hand-sewn reinforced edge pocket. The collar is a curving deeper jut neck that can be worn fully zipped or lapels splayed out. The sleeve seam arcs down the front and then towards the blade of the hand. The same seam continues through the front shoulder and then curves around the neck to meet the mirror image on the other arm at the center neck in a perfect +. The front panel's neckline curves up and around the back of the neck to help form the collar. The lines follow a continuous line of motion from one arm to the other. The hem is also curved and is slightly lower in front and then curves around the hips and up at the base of the spine. The inner lining is 100% organic cotton and forms the side curving pockets with seams that flow into the panel seams and then the double chest pockets similar to what was done on the 3rd iteration leathers. I have also designed in two matching inner side pockets that can hold more precious items and are inset so far as to be difficult for pickpocketers to reach. The hide is a medium weight and so is a trans-seasonal leather that has an incredible handfeel and structure that gives it a form even when not being worn. The Guidi calf has incredible subtleties and textures that not only look incredible but will age beautifully over time. As is with each hide, no two jackets are alike. The leather has the texture that I can only describe as a slightly "wet" feel and handles almost like soft lead. It has structure unto itself but also molds to the body and follows the human form beautifully. If you've handled MA+ leathers and/or some of the Incarnation hides then you'll know what I'm talking about. Pretty special texture and handfeel unique really to Guidi. An added lovely aspect to the Guidi hide is the presence of occasional sites of hide scarring which adds another dimension to the already beautiful leather. I took a photo of one of these spots found on the upper back/lower neck. All the seams of the leather have been painstakingly sewn and then hand glued flat on the inside an inch at a time so that every seam lays completely flat and smooth. As with all my work, each jacket is constructed by me personally from beginning to end. Measurements: Shoulder- 18" Chest- 20.5" Sleeve- 27.5" Cuff- 5" Hem- 20.5" Total- 25" This was a one-off piece that was constructed by me while trying different leathers for final production use. This is the only one of these jackets made from Guidi black calf leather from the three hides that I had. No more will be produced." There are two small imperfections in the hides he used, both pictured. These are quite small and don't impact the look of the jacket at all IMO. Regarding sizing, I'm 6' 155lbs and this jacket fits me well with a bit of room underneath for a sweater. The leather on this jacket is truly awesome. It's thick but very soft and pliable, and the "wet" handfeel he describes is very accurate. Wish I could wear it more often but I have too many jackets and it works better in cooler climates than here in LA. $950 + $20 shipping in CONUS. International shipping based on quoted rates.
