I love the down shirt but would really like it even more if it came in a full zip version. I have searched around and I am still confused about whether or not the Ultralight jacket is the same weight/warmth/fill factor as the Shirt. I did an e-chat with Patagonia sales guy who said the Nano and the Shirt are the same. I don't think this is correct. The nano is 60 grams of Primoloft. I own a Arc' atom and it's 60 grams of Prmoloft and by no means is that the same as the shirt. SO.......
Can anyone enlighten me...... (BTW, I have a Large black shirt and would trade for a Medium if anyone has one)
