Bought a Patagonia R2 jacket a year or so ago, in a dark brown color. It's a size large, which is too big in the body for me. Only tried on; still new/with tags.
24" across the chest, 27" from the shoulder down to the waistline, and 23" from the armpit to the cuff. 404 grams/14.3 ounces on my scale.
In some not-great timing on my part, I'll be taking off Thursday (3/7) for a two weeks of travel and backpacking. I'll be available to talk during the first week, but not to ship anything out.
