When my old Patagonia puffy finally reached the end of it's well used life, I started looking for a replacement. I don't buy equipment often, so I want it to last. My go to brand is usually Arcteryx, but I looked at the Arcteryx Cerium LT, Mountain Hardwear Ghost Whisperer, and the Feathered Friends Eos. I won't get into the details, as I usually agonize over these things, mainly because I know I will get into trouble with Nancy no matter what I do. Suffice it to say it was an agonizing, yet fun decision. I narrowed it down to Mountain Hardware, Arcteryx and Feathered Friends. The Mountain Hardware jacket looked beautiful, and was at the top of most of the online reviews. But it only had 800 fill down, and I wanted higher, and the down was treated for water resistance, which I just did not like. I ended up ordering the Arcteryx jacket, along with the Feathered Friends Eos (the Eos was back ordered, and they did not know when they would ship). Upon receiving the Arcteryx jacket, with it's 850 fill down and it's beautiful workmanship, I thought I had my jacket. But I did not like it's $370 price tag. Plus it used synthetic materials around the shoulders, which was a minus for me. So I sent it back, after realizing I could get it cheaper on Ebay. Then I got the email saying the Feathered Friends jacket would be shipping. I was excited, as I have had a few of their sleeping bags, one is almost 20 years old, and found their workmanship and customer service to be top notch. Plus it was assembled in the US, which was nice. After I received it I was blown away. It just felt good, 900+ fill down, beautiful details. The only minor issue was the hood, with only elastic did not really fit tight enough, I think it might blow off in a high wind. But that was not a deal killer.
The medium fits slightly large on me (5'-8" 150), which I like, easy to move around in. I hardly know that it is on, not like the Arcteryx jacket that did not have the loft this jacket has.
It has performed flawlessly, I was warm for over an hour in 15 degrees, with a light shirt underneath. That's about it. I would have been happy with any of the jackets, but I am happy with my purchase, even at $340.
