New Show Jacket Advice

I posted something similar in H/J but as I do the odd USEA event as well I thought I should see if anything different is suggested.
I need a new lightweight show coat for the stadium phase of eventing. I have a Pikeur for dressage (do eventers wear Pikeur type jackets for dressage or do you wear the same as for the stadium?).
I have an English show coat that I used to wear for showing AND eventing in England. It’s a Ratcatcher so proper for the lower levels of eventing in England. Here it is:-

I used it for the dressage and showjumping phases:-

I’d like to find a jacket that is as versatile for here, I haven’t seen anyone wear a jacket like my English one and tbh it’s really hot as pure wool and I think I might die in the CA heat jumping in it.
So a very long winded way of asking for suggestions for a lightweight show jacket that can be used for jumpers and eventing that is cut in the shorter style (as I’m short myself) and is suitable for a hot climate and looks fashionable.
Thank you!!

I have this coat: https://www.smartpakequine.com/pt/equine-couture-raleigh-soft-shell-hunt-coat-10291 I LOVE IT. Washes really well. Fit is very nice. I love the double-vented back. I wear it for both dressage and stadium. It’s clearly a hunt coat, tho. The RJ Classics soft shell for $218 is also lovely.

That is very nice, I love the price! It won’t matter if it gets slobbered on. Thanks

Devon-Aire has a new machine washable, water repellent jump coat that just came out. It is very light weight and is modeled after the European coats. It retails for only $130!

Not sure that this is really what you are after, but I wanted a really lightweight jacket (live in Australia) and bought a kerrits one.
The material is not particularly luxurious I suppose, but it’s definitely lightweight and very low care!

I wear it for straight dressage and eventing dressage/showjumping:
