Winston for the brown coat: https://www.winston-equestrian.com/usa/jackets/devon
I should come clean, however–I got that used from Ebay or Chagrin Saddlery and got stupid lucky with the price. New they are REAL expensive. But especially if you are a fuller, curvier rider whose body mesh-y tech fabrics don’t always love, this is a great coat. I’ve got two (both used). Reminds me of my early 2000s days but washable.
RJ Classics Monterey for the gray coat: https://rjclassics.com/products/new-monterey-show-coat-blue-weave
That’s an older one–I vividly remember getting it on clearance in like 2020. BUT, they do have some lovely charcoal variations atm. And they do cycle through lighter gray coats every 2-3 years it seems. I do like this tech fabric more than others because it’s got more structure to it and fits boobs and broad shoulders unlike some other brands.
