Our Verdict

Feathered Friends has been making some of the best down sleeping bags on the market since 1972 in Seattle, Wa. The EOS is a stellar jacket made with some of the best materials and filled with some of the highest quality down of any model in our review. It comes in at a very close second to our Editors' Choice, but it wasn't an easy decision, and this almost took it this year. The warmth to weight ratio is hard to beat, and this jacket also reigns supreme when it comes to compressibility and stuffing away easily into its included stuff sack. It's clear Feathered Friends knows how to produce top-notch down products without cutting corners to save weight or production costs.

Our Analysis and Test Results

The Feathered Friends Eos uses 900+ fill-power, responsibly sourced down, which alone sets up the Eos to perform well in our warmth, weight, and compressibility metrics. With a simple yet functional design, this jacket is a go-to in the eyes of our testers.

Performance Comparison


The more loft a jacket has  the warmer it is  and the Eos by Feathered Friends was one of the puffiest.
The more loft a jacket has, the warmer it is, and the Eos by Feathered Friends was one of the puffiest.

Warmth


First off, the Eos Packs a lot of puff. It's visually apparent that this jacket is loftier than most of its competitors. Feathered Friends does not skimp on down in the hood or collar either, giving the Eos a sleeping bag-like feel when it fully zipped up. However, one of our only complaints is that the hood doesn't have an adjustment to seal out cold air.

The Eos has about twice the loft of the Mountain Hardwear Ghost Whisperer 2 Hoody  making it significantly warmer.

Weight


On our scale, a size large Eos weighs 13 ounces with its included stuff sack. While that is heavier than a few others, it isn't in the same class when it comes to warmth. Many ultralight style down jackets will struggle to even come close to the warmth of this. If warmth to weight were a metric, this would hover at the top.

For the amount of warmth this jacket has  it's amazingly light. Weighing in at 13 ounces for a men's size large  this warmth to weight ratio is hard to beat.

Water Resistance


The DWR treated Pertex Quantum shell fabric performs well out of the box, repelling water for about five minutes during our shower testing. After five minutes under a high-pressure showerhead, water began to leak into the inside of the jacket where the baffles are sewn through, but the down never went totally limp, an admirable performance for a down coat without hydrophobically treated down.

The DWR coating worked wonders and didn't wear off after months of testing.

Fit


The Eos has a great fit, perfect across the shoulders and torso, and just a little baggy around the stomach. This causes it to seem slightly bulky under a shell but gives it the advantage of being easy to get on over other layers at a windy belay or on a ridge during a ski transition. The hem extends a few inches below the waist, but it's not as long as a few others in the roundup. The hood fits well and stays in place without a cinch cord, though it's a smidge too tight when worn over a helmet.

The fits well  hugging the had and keeping our tester's ears warm. we feel that its a tad small to fit comfortably over a climbing helmet.

Compressibility


Once again, the 900+ fill power down gives the Eos a big advantage. All that puff crams down into an included stuff sack. Pull it back out, and it lofts up quickly, again and again. This jacket is one of the thickest and warmest in our review and packs down just as small as other models that aren't as warm or as lofty.

This jacket didn't pack the smallest  but being one of the warmest jackets tested  that was to be expected. Regardless  the 900+ fill down definitely helped it get relatively small.

Features


Our only real complaint about the Eos is its hood. As mentioned, it doesn't feature an adjustment to cinch up around the face sealing out the cold but instead has an elastic brim that fits well enough on the average head, but it's a little too small to fit over a helmet. Many of our testers are climbers and prefer a hood that fits over a helmet, but if these issues aren't a concern, then the Eos has all the features you need.


Two zippered handwarmer pockets keep your small, important items secure. There are two pull cords on either side of the hem to cinch down the waistline and seal in the warmth, but it's missing a place to keep the cords out of the way, leaving them vulnerable to getting caught on carabiners or brush. We just tucked them up inside the coat, which works just okay. As mentioned before, the Eos packs away into an included stuff sack, not a built-in pocket. We prefer it when a jacket stuffs into its own pocket because then there's no stuff sack to lose.

This hoody is light and compressible  so you've got no excuse not to bring it along and pull it when you stop moving.

Value


The price doesn't seem outrageous for an awesome jacket full of the best down available from a small Seattle based company, making the Eos the "bargain" of the top performers. If it had a cinch-able hood and a better-designed hem tensioning system, this may have edged out the Editors' Choice and would be a screaming deal.

Staying warm in this packable jacket makes it easier to endure long  patient belays in the shade (your friends will thank you) or strolls around town.

Conclusion


This season's round-up of down jackets features some great models, and picking our favorite came down to some serious hair-splitting. We wanted so badly to give this our Editors' Choice, but when it came down to it, it honestly falls just short of being the most useful.
