Women's MicroTherm® Stretch Down Jacket



Live Your Adventure®

Both the shell and lining of this newest version of our iconic ultralight jacket are stretch fabrics for superior mobility. As before, the 800 fill Premium StormDown® retains its insulating loft even in wet conditions and allows for exceptional warmth without weight or bulk. Patented MicroTherm construction keeps the high-loft StormDown close to the body for maximum thermal efficiency and minimum bulk.

"The MicroTherm Stretch has found a place in my kit for alpine rock and multipitch climbing due to its durability and stretch. It provides the right amount of warmth on cold climbing days, and has been really resistant to rock abrasion, making it a go-to piece for those chilly summits."
Katie Lambert, Eddie Bauer Climbing Athlete

MicroTherm™ Down

MicroTherm is First Ascent's lightest, warmest down construction, which pairs Premium European Goose Down fill with some of the narrowest channel baffling in the outdoor industry. The narrow-channel construction prevents down migration and keeps the fill more evenly distributed throughout the garment—minimizing the cold spots and filling voids that could allow body heat to escape. This elevates the overall thermal value of MicroTherm to an extremely high degree, meaning more warmth for the same weight, reducing overall bulk and allowing for easier layering as well as greater packability. We like to emphasize it's the warmest, lightest down we've ever made.


Our durable water-repellent (DWR) finish causes moisture to bead up on the surface so it rolls off or evaporates rather than soaking into the fabric.


Every product we sell carries a lifetime warranty. If you are unhappy with it for any reason, you may return it for an exchange or refund.

Awesome Jacket!!


Jacket fits true to size. I'm 5'2, 125 lbs and I bought a size small to put under a shell jacket for snowboarding (size small leaves me a little bit of room to put a heavier sweater if I want). Very confortable and non restrictive.




Runs very small


This is a well made jacket but ran extremely small. I ordered a medium which is my usual size at Eddie Bauer and I could not even zip the jacket up all the way. I would say size up two sizes.




Great everyday jacket


This jacket fits great. It's more of an hour glass shape & not boxy with a good length for my long torso (I'm 5'5" & ordered a regular small). The stitching pattern down the back & sides is flattering. The flex (stretch) of the jacket makes it comfortably move with you during activity & it can be worn under a base layer plus another medium weight layer without getting too tight. There are a few down feathers that come out at the stitching from time to time, but since I got this for an amazing sale price its a small inconvenience. The jacket is lightweight & packs easy.

Fantastic Jacket


I am very very active! And I live in a rainy area… This jacket is absolutely perfect for my commute/walk to work underneath a rain jacket! It fits beautifully, it's comfortable and exceptionally warm. I wear this jacket almost daily… It doubles as a sweater as I wear it dailly all day. In fact, I have two jackets!
