it is, and that is lamb; to be really honest, I prefer lamb for everything. They're obviously not jackets for really riding a bike in, but lamb falls nicely on your right out of the box, you can wear it a little slimmer because it stretches and doesn't crease hard in your elbows or pits like the harder leathers do, and it looks really fucking cool when you have a Bomber in A-2 style but it's cut trimly, see what BoO is doing this season (and what I've done for 2 years now with the Bomber - I<3Bacon wears the very first prototype and wears it well, it may not even come across slimly enough in pics but it definitely is, because it was made for me ) The thick lamb we have (which is all of those colors except the red, which is mid-thickness) is something really nice, not run of the mill stuff. That's why I tend to use it on all sorts of things, like varsity jacket sleeves, coat trimmings, there will be more; it's 'ours' if anything were. Other makers make leathers in Korea here using the same garment leather sources that we do, like Geller, etc, but they don't step up the extra $1-2/square to the nicer lamb that we use, because a larger sized leather jacket with detailing can be 50 squares per jacket. They tend to stay with the thin Italian nappa hides that are more standard and run fairly cheaply, it's genuine leather as opposed to full on aniline dye leather like I prefer to use, which has a transparent, deep finish with several color layers and a full grain, as opposed to the painted-on opaque finish that covers blemished or split-down hides. yup, mine's the light grey lamb in A-2 style. true to what drew said, lamb just feels nicer when worn because it is so light yet durable. I only wear the calf varsity when I feel that it's going to rain or when it's really cold. also, lamb just ages so well, it feels like it gets softer with every wear. And when I saw what BoO did with the bomber, I was just thinking to myself, "I rocked that style one season ago." Just proves that the classics are always in style as with TOJ. my bomber may not look that slim, but when it is zipped up, it really fits like a glove. great job TOJ.
