Women’s Mountain Side™ Windbreaker is rated 5.0 out of 5 by 24.
Rated 5 out of 5 by from Exactly what I wanted I have been "in the market" for a windbreaker for years. I am a very petite woman (4'9" and 102 pounds), and even extra small sizes have been too big, or the arms have been too long. If I try on children's sizes, they don't accommodate my hips. I held my breath as I ordered this, and assumed it would be going back -- but it is perfect! We hike year round, but fleece can be too warm and cotton shirts don't shield from the wind. I am very excited to take this hiking in the weeks to come. And the white sleeves and body are a bonus as we hike in deer tick habitats. Thanks, Columbia!

Rated 5 out of 5 by from The jacket I have been looking for! I wanted a half zip rain coat for when I leave for Costa Rica because I just can’t be bothered with the full zips. I fell in love just by opening the package! Runs a little big but it’s only really a problem for me because I fit inbetween a medium and large! Columbia products never let me down and last forever!

Rated 5 out of 5 by from Love it! This fits so well and it’s really comfortable. I’m 5’1” and about 130lbs - bought a medium so I could layer under it. Great to help keep me dry on drizzly days during my trip in Ireland

Rated 5 out of 5 by from Great I was looking for something lightweight that I could take along on walks when it looks like there's a chance of a little rain or wind. Paired with a fleece sweater, it's quite cozy and warm. The snaps on the front are hard to open and it seems like the fabric might rip if you aren't careful.

Rated 5 out of 5 by from Windbreaker I love this! It’s thin so perfect for a rain shower all year round! I wish I had purchased this for our Orlando vacation this summer, would’ve been perfect! I know to bring it next time!

Rated 5 out of 5 by from Perfect Fit I'm a 5'10" female and the large fit me perfectly. Great to wear when damp weather - won't keep you warm but over a fleece or something else and the job is done!

Rated 5 out of 5 by from So cool that my son already claimed it! Bought this jacket for myself to have in case of pop rain while hiking. My son saw it and decided that he needed it for his backpack when he heads off to college Very lightweight and rolls up nice and compact I’ll probably by another one but in a different color so we’re not twins!

Rated 5 out of 5 by from Lightweight windbreaker Fits well, lightweight, packable, wind-resistant and rain-resistant. Not fully waterproof, but good in a light rain or on the boat. The white color is translucent, so you can see whatever you are wearing underneath. Really nice for the summer!

Rated 5 out of 5 by from Great selection Love the color, it is a lightweight jacket that is perfect for summer rainstorms or you can layer it over a flannel for colder fall storms. The design and fit is great!
Date published: 2018-08-04
Rated 5 out of 5 by from Lightweight with hood. Perfect for an upcoming trip where layering is the plan. True to size, but large enough to layer for cool mornings into warmer afternoons. Rainy weather expected so the hood will come in handy. Love the color in turquoise with yellow banding. Just ordered another one in a different color as I love this parka.

Rated 5 out of 5 by from Mountain side windbreaker Very nice windbreaker. I have my old Columbia windbreaker that I have had for 25 years. It even held up when I crashed on a motorcycle. No rips or tears!!! So happy to see this style again.
