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.

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.

Instant favorite

I've been eyeing this for a while and decided to buy it in October for the colder rains in the fall. I brought it to my race in Savannah and glad I did. The jacket kept the rain out for the 13 miles I ran but also kept me cool which was surprising as I always overheat in a jacket. The race was also the first time I wore it and no issues there.

Perfect rainy day jacket!

My new Rainrunner jacket was perfect for a duck weather run in Seattle this morning - it kept me dry while still allowing for ventilation. I love that it's small and light enough to keep in my backpack when I travel.

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. :)
