Feathered Friends Men's Eos Down Jacket

Named for the goddess of the dawn, we designed the Eos jacket for early morning starts that call for an extra layer of no-fuss insulation. With just the right amount of premium 900+ fill down, this hooded down sweater excels at keeping you warm on its own when conditions call for moving light and fast, or as a layering piece when weather moves in. Equally at home on the trail or around town, this lightweight and packable jacket will do wonders in your outerwear quiver.

Great JacketReview by Brian
I bought this jacket as a first step to ditching my sleeping bag and moving to a quilt for ultralight backpacking. I just finished a 4 day trip to the Sierra where we slept 3 nights at 11K+ feet with night time temps at 50 degrees, 35 degrees and 30 degrees for the three nights respectively. With my bag unzipped and pulled below my neck this jacket was a great substitute for a mummy bag and kept me warm on both of the colder nights (I had to remove it on the 50 degree night as it was WAY too warm). This jacket is much warmer than the name brand down sweater we are all familiar with.

What I really love about it is how much better the handwarmer pockets are than my last down jacket. My only wish for this jacket would be an inside chest pocket.

I ordered this last minute with a comment that I needed it by a certain date and it arrived a day earlier than required, now that is customer service to suit such a well crafted jacket. I will be buying my wife one for her birthday this year (SHHHH dont tell her ;) (Posted on 7/20/2017)

Best........ ''Sweater''....... EVER!Review by RUBEN
I just purchased the Eos in January and here are my initial impressions. Although FF bills the Eos as a ''sweater'', it is really more of a light jacket. I also own a Patagonia down sweater and the Eos blows it away in terms of warmth! I am cold -natured so I was a bit concerned the Eos would not keep me warm. The Eos has probably twice the loft of the Patagucci, and is 900 fill vs. the 800 fill of the Patagucci. The trim fit of the Eos also contributes to the warmth, I believe(less dead air space).

WARMTH: I tested the jacket in my backyard one morning. Temp was 30deg F. Windchill of 18deg F. I was wearing a capilene baselayer, and an Ibex wool zip-t. I was quite comfortable for the 30 minutes I was sitting out there. I specifically wanted to simulate sitting around camp as opposed to being active while wearing the Eos.

FIT: I am 5'9'', 185 lbs, 34 inch waist and bought a size large. The Eos fits me really well, it's just a little snug in the armpit area. It's nice and snug at the waist which I like.
The elastic cuffs could stand to be a bit smaller to better seal the wrists. Hood fits well over a beanie.

LAYERING: I can wear the jacket comfortably over a baselayer and trim midlayer such as the Ibex Shak, or Patagonia R1 fleece. Note: I did manage to wear the jacket over a baselayer and my ArcTeryx Atom LT, but it's a little tighter.

WEIGHT: Size LG Eos came in at 13 ounces exactly, in it's stuffsack, at my local Post Office. Outstanding!

CUSTOMER SERVICE: This is my 4th product purchase from Feathered Friends. I got some great service from Neil, Michael, and Wes. I do not live in the Seattle area and so I had some concerns buying long-distance. Neil was especially helpful.

BOTTOM LINE: The Eos is the best down ''sweater'' on the market. 13 ounces, 900 fill-power, and super warm for the weight. BUY ONE! (Posted on 2/4/2017)
Fantastic Light Weight Jacket!Review by Josh
This is my first FF product, but I was familiar with the name and the great reputation that came with it. A friend of mine recommend to me that it's time for me to give it a try, since my now retired down jacket needed to be replaced. I was conflicted as to whether to go with the lightweight or mid-weight jacket. Since I generally create quite a bit of metabolic heat, I decided to go with the lightweight. I've actually been too warm at times with a long-sleeve shirt underneath in high 20s to low 30 degree temps. I live in Buffalo, NY and we have a pretty notable reputation for our long winters. The other day I was gathering wood for some projects on the edge of Lake Erie on a cold and windy day! I was getting sprayed with freezing cold mist, but this jacket held up incredibly! I'm 5'5" 163lbs and the medium fits great and with room to spare underneath for additional layers. Well done Feathered Friends, this certainly won't be my last purchase from you and I'll continue to spread the word that your reputation carries! Thank You. (Posted on 1/29/2017)
An excellent light weight jacket Review by Bill
Just returned from trekking in the Himalayan mountains in India. In breezy 30 degree temps at 12+ feet altitude, the Eos layered nicely over a fleece midlayer and kept me quite comfortable while in camp. Quality is excellent as would be expected of a FF product. It also packs down nicely for travel. Overall, I'm quite pleased with this jacket. A perfect lightweight and warm addition to my gear. (Posted on 11/3/2016)
A lovely jacketReview by Ival
This is a lovely jacket. I highly recommend this for cooler Seattle evenings and summer camping in the Cascades. I love the hood. It has deep outside pockets and a nice drawstring at the waist; I wish my Volant had a drawstring at the waist. If only it was waterproof. (Posted on 7/3/2016)
Top notch!Review by Nathan
The quality of this jacket is excellent. I placed an order for a few other down jackets to see which one fit me best, but as soon as I saw that Feathered Friends made a jacket I knew I would be returning the others. I tend to be a large from the chest up but a medium from there down and this jacket fits me perfectly. If you are looking for a down jacket I would definitely keep this near the top of your list.
