Features

With 4.0 ounces of 900 fill power down, it is the warmest sweater-weight down jacket in our guide, and 37% of its mass is down. It looks like most other down sweaters, but it’s noticeably warmer when you have it on.

At 10.8 oz, it’s a bit on the heavy side for ultralight tastes, but we’re willing to forgive that because of how cozy it is. We envision this to be the perfect down jacket to use during the warmer half of shoulder season, whereas its puffier sibling, the Helios, is preferable for the colder half of shoulder season and into winter.

As features go, Eos has two zippered hand pockets, and one zippered chest pocket, as well as an adjustable hood and hem. Nothing fancy, but we prefer minimalism anyway.

Verdict

If you run cold or just want a seriously high quality, warmer-than-average lightweight down jacket, then Eos is a safe bet. We’re not surprised to see that 85% of the reviews on the Feathered Friends website gave it 5 stars.
