Review Summary
Fits True To Size
Screen reader users: the following list provides a visual scale to illustrate the product fit. Please refer to the heading above for the fit type in text.Here's what customers have to say
The reviews provide a mixed assessment of the rain jacket. Many highlight its lightweight, packable, and versatile design, making it well-suited for outdoor activities. Reviewers praise its quality, durability, and performance in light rain or wind. However, a significant number report that it is not truly waterproof, soaking through in heavy rain or downpours. Several also note issues with the fit, particularly around the hips and sleeves. While the jacket may work well for light, occasional rain, many caution that it is not suitable for prolonged exposure to heavy rain or severe weather conditions. Overall, the reviews suggest the jacket is a good option for weight-conscious outdoor enthusiasts, but may not provide adequate protection in more demanding conditions.

A Truly Great Jacket (Used Properly)
- Familiarity:
- I've put it through the wringer
Outdoor Research is a company that has steadily improved its cred in the outdoor athlete market by making lightweight feel like the real thing. This is maybe the best version of that I've seen. This thing packs up into a fist and carried me through more than one rainstorm on my bike. It is not a full-blown rain jacket. It's not meant for anything other than outdoor activities where you have to shed every ounce you can. This jacket ticks a lot of boxes if you're only bringing one on a bikepacking trip and need to remain un-hypothermic above treeline, let's say. It's a really, really good piece of gear, period. The hood is large enough to fit over a helmet, and the wrists are elastic and tapered. The jacket folds into its single pocket. It's not exactly clumsy but it takes a bit of finessing. The inside of the jacket feels like a light coating of high-quality waterproofing, and I've never experienced the problems others here have. If weight is no issue, there are many more options that would be far more appropriate, for what should be very obvious reasons. But if you're bikepacking, backpacking, or just really into great lightweight products, highly recommended.

Quality and performance in one jacket
I bought this for a backpacking trip and not only is it great in rain and wind, it’s so lightweight it is perfect for backpacking when you’re traveling as light as possible.

Lightweight Rain Protection
This will be the perfect jacket to stow away in my luggage or pack for “just in case it rains”. It is super lightweight and packs small. I will also be using it for Spring rainy days here in Oregon when it is too warm to wear my Gortex rain coat.

Wets through instantly, do not buy
Really disappointed in this jacket despite good reviews from external sites. From the moment I got it, it was not waterproof for even a slight drizzle. It wets through instantly. I tried washing it and re-treating it per OR's instructions, but it's still awful. Maybe ok as a windbreaker, but not worth that for the price. Really disappointing.

Don't waste your money
Not waterproof at all, small for size & do not recommend. Kind of worthless after a year of wearing it. Colors are good, and that's about it.

Failed in a storm
I remember when OR gear used to be absolutely bombproof -- I still have a pair of gators that I bought in the 90s! Sadly, those days are gone. Bought this jacket for a thru-hike on the Colorado Trail this past summer. It was brand new and completely failed in a torrential downpour; I got absolutely soaked, and if it had been much colder, it could have been a serious situation. I do a lot of thru-hiking and backcountry travel, and I need to be able to rely on my gear (especially when it's brand new.) I won't be buying technical gear from OR in the future. I guess this jacket is appropriate for... misty conditions? A short walk in light rain? A stroll down to the cafe? But don't trust if it you're really going to be out in the elements.

Nice But Narrow on Bottom
I’ve been looking for a very packable rain jacket to take on trips that are likely to have some rain but not much. I wanted a jacket with no Velcro which is hard to find. This jacket has none and is very lightweight so I decided to try it. I am 5’2” about 118 pounds and ordered the small thinking that would allow for some light layers underneath. The problem with this jacket and many others is they are cut so straight that there is little room in the hip area. With even a light layer it was very tight in the hips when zipped up. I wish outdoor clothing companies would realize that most women have hips!! I ended up getting a medium which fits really well except for the sleeves being too long. I can tuck them under. Have not worn in rain yet but since I will only use for light rain I think it will be fine.

Great packable rain jacket
I bought this a couple years ago and has saved me more times than I can count. It packs down super small and is incredibly breathable which is needed for us down in Alabama where it can still be very hot while raining. Since buying this I can't tell you how many times I have recommended this product to customers. Truly my favorite jacket.

long and narrow
lightweight and packable. Kept me dry on a trip to Norway. Docking a star because the fit is very narrow through the hips, but a larger size would be too long in the arms and chest.
