“Custom Leather Jacket Design – Balancing Motion and Fit”

This is a design concept I’ve been working on — aiming to create a jacket that offers European-style range of motion while maintaining the sleekness and fit typical of Asian tailoring.
Before discussing this further with a brand, I’d love to hear your feedback on whether the idea looks solid.

Leather:
• Black Oil Tanned Wax Finish Horséhide
• If that’s not available, any leather with a high wax pigment content would be acceptable.
• Thickness: 1.2–1.4mm, depending on discussion with the brand.

Pattern / Form:
• The base pattern is inspired by the Delraiser or a similar layout.
• The reason I prefer the Delraiser is because I like how the D-pocket and chest pocket run parallel to the main zipper, unlike the layout on the Buco J24.
• I’d also like to add epaulettes and side adjuster tabs at the hem.

Lining:
I’m planning to use quilted satin for the body lining.

Collar and Fur Lining:
Some members on the forum have suggested options like thermal scarves or neck warmers — I’ve tried those before. In the end, I went with the removable collar/back fur lining from a Schott 184SM and fitted it into my 611H.

It worked surprisingly well, so I’m planning to do something similar for this jacket.

This time, I want to adjust the fur size slightly — instead of using a thick, full-sized panel, I’ll keep the fur just enough to cover the visible collar surface. That way it won’t look too bulky and keeps a balanced visual.

For the body fur lining, here’s the idea:
Since the jacket will have a form somewhere between slim and straight, with a slight taper at the waist, there should still be enough room for the fur lining without making the jacket look overly bulky when worn.
(My Schott is quite snug, yet I was still able to install the 184SM lining and found it worked fine — so I believe this plan is feasible.)

Functionality:
The back panel of the Delraiser features an action back that extends all the way to the hem, which helps a lot with forward arm movement, especially when bringing the arms up parallel to the ground.

Approach 1:
Raise the armhole to increase upward mobility.
(I believe the gain in range is minimal, but it does improve the overall aesthetic and silhouette.)

Approach 2:
Add a diamond-shaped underarm gusset to further support upward arm movement.
This would help reduce stress on the armhole when lifting the arms, and allow for a more natural range of motion without distorting the jacket’s silhouette.

Approach 3:
Use a gusset similar to the one found on Schott or the Saint Laurent L17.
This currently seems like the most promising option, though it might be less clean visually.
It allows for easier lateral and overhead movement, partly due to the slightly relaxed fit on those jackets.
However, if applied to a more fitted silhouette, I believe the effectiveness might be noticeably reduced.

Approach 4:
Have them build the sleeve angle to naturally pitch upward at around 70 degrees relative to the ground.
This would create built-in range of motion for lifting the arms.
(When the arms are relaxed and hanging down, they will naturally bend at the elbow — as shown in the illustration.)
IMG_0555.jpeg

Approach 5:
Use a more flexible type of leather in specific areas to take advantage of its natural stretch.
This, combined with a higher armhole, would allow better arm lift.
(Since the leather in this zone is softer than the rest of the jacket, raising the armhole won’t cause discomfort under the armpit.)
IMG_0557.jpeg

The sleeves should be pitched forward at about 20–25°, with a natural elbow bend of roughly 45–60°, to support a relaxed riding posture while still looking balanced when standing.

I agree, most custom makers have their own pattern already, not allowed for this sort of customization. Only JL offers this kind of service, where they can build you whatever you want.

But back to the OP’s question, the five approaches get at the same functionality. If you don’t know which approach to get, then why does it matter for you to be picky about it? Why not just accept whichever pattern the leather jacket maker has and provide your measurements to get the jacket made? That’s usually how custom works, not the kind OP is imaging.

@Quan_love_leather , you're going too far in your approach. To really understand how patterns work... you should have gone to pattern school.

I will repeat the same advice I gave you: go with a maker known for great mobility in their patterns and you will get the mobility you want. And there is no such thing as "European mobility" and "sleek Asian tailoring".

A good pattern maker will make a jacket that will make you look good and give you good mobility, a bad one will make a tight jacket that looks two sizes too big.

Whichever brand you chose the maker will have to have the patience of a saint with this order/project :) JL seems your best bet.
I think even JL knows when to say no sometimes, a crazy man named HH121 from TFL taught them that lesson a few years ago. He was on a quest for the heaviest leather jacket possible but he only succeeded in becoming the worst customer possible.
I think the OP should feel free to discuss the pros and cons of the various gussets and arm construction techniques but in the end I agree with @red devil that you need to find a good maker and trust them to do what they do.

I cracked up a little when you brought up that name

I've queried and read like 10 pages of that thread and I don't even know how to explain it. Just wish I had been there to see it develop live.

Haha I know, sometimes I feel like a real weirdo. I’ve already chosen JL for this one — honestly, I just can’t stop thinking about customizing leather jackets. :)))))

Honestly, I really enjoy customizing leather jackets and have a bunch of ideas. When talking to the brand, I might still go with one of their existing patterns — it’s not like I’m against that. I just wanted to share my ideas here so others can also take a look, and who knows, maybe I’ll learn something new too. Nothing’s impossible, right bro? Haha.

Thanks for your honest feedback. I understand what you’re saying — my approach probably did go a bit too far, and honestly, I sometimes feel the same way myself
I didn’t mean to come off as stubborn or dismissive of practical experience. I just really enjoy geeking out over jacket forms, patterns, and mobility — but I know I don’t have any formal training, which is why I wanted to share my thoughts here and hopefully learn from people with more experience.
When working with a maker, I’ll definitely be flexible and likely go with an existing pattern, maybe with a few tweaks if possible. I’m not trying to “reinvent the wheel” or act like I know better than the craftsmen
Anyway, I truly appreciate your input. I’m still learning step by step, and feedback like this really helps. Thanks again.❤️

The best mobility I have ever found in a motorcycle jacket, especially in a warm wet, humid climate such as the one you live in is...a textile jacket with pads. Simple, easy, done.
That’s a fair point and I totally get where you’re coming from.
Textile with pads is definitely the most logical choice for this climate — especially when riding regularly.

For me though, leather jackets have always been more of a passion thing — I know they’re not always the most practical, but I enjoy exploring their limits. Maybe a bit irrational, but that’s part of the fun for me

Oh wow, sounds like there’s someone even crazier than me out there
I totally agree with you — I’m just here sharing my passion for customization and offering my personal take.
Think of it as a little “mental snack” — something different to chew on.
Thanks a lot, bro!❤️

By the way, if possible, could you guys tell me more about this HH121 guy? I’m really curious now — sounds like a legend

He was our very own Don Quixote but his quest was for the thickest leather possible, measured using his own calipers and scale.
He was a real character, quite blunt and to the point. For instance someone once asked why people here like Vanson so much when they had relatively basic and boring leather offerings. Hh replied that when you bought a Vanson you were paying for the pattern. In that one sentence, he explained concisely something that I probably would have droned on about for a paragraph.
Unfortunately, he was quick to sour on people, and makers, and when that happened he became quite nasty. I don’t need to rehash the details, but he picked several fights with people here and said some really rude things. That’s why he’s not here anymore, at least not using the name Hh121.

Wow, now that’s quite a legendary figure — like a leather-clad Don Quixote with calipers instead of a lance
Sounds like he had real insight and conviction, but also a bit of a self-destruct button.
Thanks for the background — I really appreciate hearing about him. Stories like this make the community feel so much more alive.
I just hope I won’t be the next person to get blocked around here
Honestly, I’m just trying to connect with everyone and share some of the ideas constantly bouncing around in my head.
If I ever get the chance, I’d love to study tailoring properly someday — maybe then I can finally give my overthinking brain a worthy outlet

I mean when you acuse makers of sending you brand new jackets with defects like that you are going to "sour on people", any body who has dealt with Stuart knows he wouldn't send this out:

Similar things happened under his previous handle "HammerKlavier".

Let's not build statues to that guy, if he was a legend it wasn't for good reasons...

So from what you guys are saying, this guy has a history of messing up jackets himself and then blaming the maker? If that’s the case, that’s pretty serious. Especially when going after names like Stuart — from what I’ve heard, he’s known for being meticulous, so it’s hard to believe he’d send out something with obvious defects like that.
Sounds like this whole pattern of stirring up drama on the forum might’ve started way back when he was using the HammerKlavier handle. If that’s true, then this wouldn’t be the first time.
