"I think they measured aliens to size this jacket"
I was so excited to get my own custom jacket! Then, extremely disappointed. The jacket fit so terribly that I had to return it. I am 5'6", 130 lbs, with a thin/athletic build. I usually wear Small or Medium (4-6). I ordered a Medium. The tapered sleeves were uncomfortably tight over my forearms, and the cuffs too tight on my wrists.The middle is boxy, and raising your arms is out of the question without lifting the whole jacket up over your torso. If you are a tiny woman with stick-thin arms and a big stomach, this jacket might be for you. Otherwise, wait until they re-design it. The materials seem really nice, but I can't give much feedback since I didn't get to test it out.
Okay, half the fun was the configurator. Moosejaw was awesome; I got the jacket 4-5days after I ordered it and it was even better made than I thought. The fit was great (5'5"/140lbs) for me in a M with room to spare. I love the insulation for blocking the wind. I wouldn't use this to SWEAT in a ton as the sweat won't vent all the way through, but for a midlayer, it's super warm and toasty. I just went running in it (I opted for the bright orange/black zipper/delft accents) and it was super comfortable and great at keeping the wind away. Hood is great and many nice touches like the soft material on the chin and the high front to keep wind out when you zip it all the way.
