Ok....cutting to the chase....I love this coat. I have highly specific requirements in a coat: hood, zip/snaps combo, super warm, water resistant, must accommodate heavy blazer/light coat as topper/huge wool sweater (yes, I am a snow beast), double zip a plus, sleeves must run long, length car coat ideally 36" I have been watching Pendleton since Anna raved about the quality (and as we know, Anna knows quality) and I adore my Pendleton Willhem blazer for it's amazing fabric and unique construction. The Pendleton Darby had everything on my wish list - including a small zip pocket on the left sleeve and a buttoned inner pocket built into the lining on the left side. The pockets are lined in a soft fleece material. In addition to the fabric being water repellant wool, there is some kind of lining that stops wind but it is listed as completely breathable and seams and zippers are sealed and it has pendleton's classic glacier park lining (which even I, Princess neutral, think is kind of fun), and I believe that give a donation to the national parks when they sell a coat with this lining. I ordered the small and the medium, the medium arrived today. Sizing is TTS. I usually am a size 4-6, 5'3" 112 lb, 34 A, slim rectangle. Due the the layering I do, I will probably keep the medium. The arm width and arm set made the thickest layers easy to get on and off. The shoulders fit me like the model- shoulder seam slightly beyond my shoulders but not by much. The body is commodious and I had no trouble fitting my thickest layers. Without layers, the coat, although oversized, still draped gracefully due to the quality of the fabric and front seaming. The sleeves run long, and I have long arms, but that's the way I like them on winter coats so my gloves are well covered, so I would not want them hemmed, but if you prefer them shorter they might need a tweak. The double zip is very heavy duty. The length is inaccurate on the website. It's listed as 33". This is fingertip length on me (long blazer girls know this stuff). This jacket runs a good 3" longer, I would say about 36", so it's about 3-4" above my knee which is the perfect length to cover all but the most excessively long layers. It's high 90's here and almost 100% humidity so although it's impossible to tell how warm the coat will be, I was roasting, which I took as a very good sign. The cut is very graceful and flattering, high zipped funnel neck, but lays nicely open if you leave it unzipped. Hood is big, too big, but can be positioned back a bit and seems to be amenable to staying. But I almost always find hoods to big. Assessment - this is a fabulous coat for the money. So many really nice details, construction is excellent as is all finish work. If you don't plan on excessive layers take your normal size. If you do the snow beast thing, size up. If you live in a mild climate and only wear thin layers you might want to size down. But if you need a sleek, elegant, classy casual winter coat, highly recommended.

PS I was concerned Angie mentioned something about "plastic" in her description of the coat. I thought the material might have some weird treatment. No "plastic" in sight - warm soft, non itchy wool, smooth satiny lining, warm fleecy pockets. So no worries!!
ETA: The coat actually feels much heavier weight wise than it looked. In fact, I though the box was too small for a coat but was unexpected heavy when I picked it up. It doesn’t feel too heavy on, but feels substantial.

ETA 2: Just wanted to update the small came today. It definitely fits plumb in the shoulders, good arm room and plenty of room in the body to layer. I would recommend take your normal size - it's a winter coat so you need room to layer - I would not size down. OTTH being princess snow beast, with my thickest layers I had to wiggle into the arms. I don't like that, I'd rather something roomier that glides on over everything. So I did keep the medium but I would not recommend sizing up unless you plan on super heavy layers like me.
