“Awesome value”

“Lots of reviews discuss problems with sleeve length and chest, but almost none give measurements. So, for reference: I have 17 1/2" (44.5 cm) arm length, 34A chest(US). I bought the Medium. Sleeve length is perfect for me, elastic comes exactly to my wrist, and I have plenty of room in chest. Agree with others that shoulder area is a little puffy, but it doesn't detract from fit(I got some second opinions as well), and it gives room to layer. Also, I was able to stuff jacket into its own pocket as easily as fitting a down sleeping back into a stuff sack - which means you do have to put a little energy into it, but it will fit. I bought this specifically due to the warmth/weight ratio so that I don't have to haul a bulky winter coats when traveling. I'm able to fit a standard W's Med. Gore-tex paclite rain shell over it for weatherproofing, which makes a very good packable, lightweight winter travel combo.”
