Our new Rainrunner fabric has a C6 DWR finish for high-performing, long-lasting water repellency and faster dry times. C6 DWR is made from short-chain PFC's (perfluorinated chemicals) that, while better than long-chain PFC's, we recognize are not environmentally ideal. We are actively testing and looking for an alternative to C6 DWR finishing that will not compromise on the performance of our Rainrunner fabric as we transition to more PFC-free bio-based water repellent finishes.


Our Rainrunner fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Ready for the wild!

It rained the day that I got this jacket and it worked like a dream. I stayed dry and didn't overheat! Now I know I can trust it for longer runs in wild landscapes.

Throw Away Every Other Rain Jacket You Own

They did it. They made a rain jacket that does it all and fits like a glove. I am an ultra-runner and ALWAYS pack this jacket with me in my trail pack because it packs so small and I know I can rely on it to keep me dry. WELL DONE, JANJI.

Love it!

Jacket is lightweight and fantastic in the rain! Also can’t say enough about zippered pockets!

Bought it and the rain stopped! Looking forward to trying soon!

Really awesome jacket

I've worn it on multiple runs so far between 15-40°F in the Midwest as an excellent layer to protect against wind, rain and snow. The hood works amazingly and keeps cold air out even with a baseball cap underneath. The sleeve cuffs also keep that cold air out! The pockets and zippers are nice too, although I've not used the chest pocket yet as my phone doesn't fit -- maybe Janji should put dimensions of that pocket on their website.
I enjoy putting this jacket on too because it just looks great and the Canyon color gives me life. I'm 5'0", 110lbs with athletic build. I purchased a S so I wouldn't have to worry about layering underneath and shoulder mobility (can't wait to rock climb in this!). I was worried the S would swamp me - it is a little oversized on me but it impressively still works. I'm happy with the extra length of the jacket and sleeves to further protect me against the elements. Time will tell how long this jacket lasts but construction looks great. I hope to wear this jacket all year for a long time.

Great jacket!

I wore this on my first cold run and it kept me very warm. The color is beautiful and is great for visibility. I am 5’2” and ordered a medium. The torso gives me room for layering, but the sleeves are a tad long. I plan to keep and enjoy for many cold/rainy runs. :)

Excellent waterproof running jacket!

I use this jacket for wet runs in the Pacific Northwest. So far, it has held up wonderfully. I am 5'6" and 120 lb. and ordered the small. I have a long torso and was concerned that it would not be long enough, but it hits at just the right spot at my upper hip. Air flows well through the jacket without making you cold. A great purchase!

Breathable!! 🙌🏼❤️

Very comfy, fits great, but most importantly it does the job very very well!!!

You Won't Overheat!

This latest Janji release has been my favorite, and I've loved every item that I've gotten from it. But by far my favorite has been this jacket. When they say it's ventilated, they mean it! I've worn it in snow and rain, in sub-20 degree weather, and warmer weather too, it's simply been awesome anywhere. It's very easily packable whilst on a run, and the integrated stretchy and soft strap for carrying it is great. I also love that you can stow the hood away with the integrated loop (the zippered ones are too bulky, so this is better). And that Canyon color, whoa, it's beautiful! It looks more orange on the website, but in person it's actually a very pretty burnt gold (is that even a color?), and not at all obnoxious or loud. The material is soft and stretchy, and not at all noisy like any other rain gear I've used in the past. Another added bonus is the hood... it stays in place! I could go on and on about how much I love this thing, but it seems everyone else already has :)

Best running rain jacket ever!

I love this jacket! I needed a new rain jacket. I figured I would mostly be using it for training (as opposed to racing), so I wanted something functional under any rainy circumstance, whether it was 35 degrees F or 60 degrees F. This definitely fits the bill! It's breathable and protective. Lightweight, but still provides plenty of protection. Great for running or hiking in any rainy/misty condition. Best money I have spent in a while!
