“I am a 6', 180#, 36C, size 12/14 woman, and got the large. I was worried about it being too tight based on the measurements, but there is room to spare for underarmor + t-shirt + hoodie underneath! The sleeves are long enough even for my 6' wingspan. It's a hair shorter than I expected - I am mostly legs with a short torso and it is still barely long enough - doesn't quite hit mid-hip as advertised. However it is flattering and sleek both with and without layers. The jacket is quite warm and windproof even without layers or the heating elements on, but very warm with both of those. I was comfortable sitting still in ~28 degrees for several hours. There is fleece where you would want it - inside the hood, inside the collar, and inside the cuffs and pockets. My biggest complaint is that the accompanying standard sized battery does not last as long as advertised - on first use, mine was charged to full, used on low for 3 hours, and was down to 25%. Luckily you can find generic versions of Ororo's larger sized batteries on Amazon for much cheaper! Overall I am very satisfied with this purchase.”
