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.

So glad I pulled the trigger on this jacket!

I kept holding off on purchasing this jacket but finally pulled the trigger and so glad I did! It's everything I'd imagine it would be and more! It's lightweight and kept me dry in the rain. I also like how breathable it is and how small it can pack. I plan on using this jacket for my winter/wet runs, hiking up 14ers & on my Alaska cruise! My search for the perfect rain jacket is finally over!

A life changer!

This jacket arrived early. It runs snug and ordered a size M instead of S. The small was a little to snug for arm movement. The Medium looks a little big, but I love to wear layers. I rode my bike (the arm sleeves are long enough to protect hands) to run a half marathon in pouring chilly rain. This jacket stood for what it promised. It kept me dry and warm. The hat fits over a running cap to keep the rain out of the eyes and stays put even in strong wind. This jacket is a must in your gear running and biking.

Wow! All the features!

I got their newest color, ultramarine. Thanks for introducing this gorgeous shade! This jacket lives up to its description and then some. The pockets are roomy and sturdy. The ventilation is fantastic because it's unrestricted and it fully goes around the mid chest: near the pits, in the high abdomen area, and across the back. I'm a very hot person and sweat to death, and this thing is the bomb for ventilation. I thought my old jacket with pit zips was going to be hard to replace, but Janji is here to save the day! The hood has a unique shape and cut that won't allow it to fall back at all, and also covers well without limiting vision. One reviewer says the collar corner will jab into your face, but I can't figure out how that could be, and it's not an issue with my jacket. Another one says the zipper head bounces noisily; maybe they have changed it, but no. The sleeve cuffs are partially elastic so the cuff stays where you put it. I have pretty short arms and appreciate this. The website specs mention laminated fabric. I was a little worried that meant the lining is physically fused to the outer layer, but there are definitely two separate layers which in my experience is more durable. This is a wowser of a jacket! I used the size chart and think this coat runs true and it will leave me room for layering. It's long enough to cover my tush. I plan to use this on an extended hiking trip as well as running.

Best jacket ever!!

Seriously the best jacket ever! I wear it everyday to run in the horrible Ohio weather. This winter has really put it to the test. I wear a base layer of merino wool underneath and that’s all I need for weather ranging from 5 degrees- 50degrees! I wore it in freezing rain this week& I remained dry for my entire run ( minus some sweat )! Crazy right/ but believe me- it’s the best! Don’t even hesitate to spend the money- I’ve been running for years and this jacket is by far the best out there!

Everything I hoped for

It’s roomy enough to layer over a top and a fleece but not at all bulky. Glad I didn’t size up. Sheds rain well, the hood is generous, the length is perfect.

THE rain jacket for PNW fall/winter

I live in Washington and the rain is truly unrelenting. This jacket is great mainly because of the super vents around the entire mid-section so you don't end up running in a sweat greenhouse like other waterproof jackets. I've tried so many different rain jackets for road and trail running and this is the clear winner so far. I'm normally a size small and purchased a small in this jacket and it's roomy but great – it fits over a hydration vest but isn't too big. I love the slightly long sleeves to cover hands in the rain too and the hood-keeper is really a great touch.

Perfect Gift

I bought this jacket for my wife as a birthday gift and it's great. We live in the Pacific Northwest so a good rain jacket is necessary for any outdoor activity. It packs away nicely and vents well.
