Thanks! I’m experiencing the cold conductivity of CXL that you’ve mentioned before with my FQHH Hooch Hauler and thought your approach with the moleskin sounded like a nice way to counter balance that.

That was exactly my plan. However, I have to say that it only partially turned out as planned. The moleskin is a little warmer than cotton drill, but nowhere near enough to make a warm jacket. I think it needs different leather (e.g. Vicenza or sheep, goat, all of which I find warmer) and a wider cut.
But I still like the moleskin because it's very comfortable to wear. I find moleskin and cotton satin the most comfortable, then cotton drill, then wool tartan.

Although I’ve had jackets, leather or otherwise, which had moleskin linings none of them had this for the sleeves. All were stock and not custom orders.
I think there’s a very good, practical reason why manufacturers don’t use moleskin in sleeves and that is because, as Mr P. suggests, it would be far too ‘grabby’. This would make taking the jacket off, and especially putting it on, a real chore. I can see that that the cuffs of whatever you’re wearing underneath would have to be held when putting your arm into the jacket. Otherwise they’d probably end up somewhere around your elbow.
I believe any possible thermal benefits of the moleskin will be very minor and not really noticeable, but even so these would be far outweighed by the issue of wearability.

What makes VIcenza, sheep and goat warmer leathers, in your experience? Would you consider Badalassi (or other cowhides other than CXL), deerskin, or other horsehides (not CXL) to be warm?

Perhaps because the leathers mentioned are "drier"? I don't know exactly, but I would most likely compare it to wearing a thin fabric jacket minimally damp (CXL) vs. the same jacket dry (goat, sheep, ...). Perhaps exaggerated.
The CXL contains a lot of grease and wax and is therefore "wetter" than leathers, which have less of it.
Whatever it is, I can tell the difference. Badalassi also seems a little cooler to me.
All this doesn't really speak in favour of leather jackets, because my comfort zone really only lies within a narrow temperature range, ideally around 12 - 20 Celsius. Too cool underneath quickly, too warm on top. And yet I still like them LOL
Always assuming the lining is not explicitly there to keep you warm.
I used to have a leather jacket lined with felt/thin woollen blanket, which was reasonably warm (motorbike), now I have a Rugged West with padded lining, which is probably my warmest leather jacket (excluding shearling).
Incidentally, I have a pair of leather trousers made from chamois-tanned deerskin that don't feel cool at all.
