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.

Great purchase

Really pleased. Breathable, not too noisy, like the length over the tush and genuinely waterproof so far. Great colours too! Would prefer the mesh pocket to be slightly larger as it’s hard to get the phone in but I guess it has to be compressive. I have 39 inch bust and 43 inch hips and the L is a good size

Love the packable rain jacket

I was a little hesitant because a previous poster wrote that she was big chested and had issues zipping up. I am 4'10, size 30FF ordered a size small and am super happy. I am able to zip up fine with no issues. I ordered it for running when it's raining in London. It has worked great. I haven't used it in down pour level but for everything else. I've also ended up using this as a windbreaker since it packs down so small on some long weekend trips. Love that I can have something for when the weather chills up at night (I wouldn't say for cold weather but more for when it's warm out but then drops at night). If you are on the fence I would buy it. I got lucky that it was also on sale so even more happy that I got it. Took off one store because I thought the cap could be better for the rain - I have to adjust it a few times when it's raining.

Lots of good. Some not.

Overall I think this is a good jacket. I love how light it is. I love the ventilation. I love that it packs small into its own pocket. It is a great jacket for exercise.

Except, parts of it can wet out pretty quick, especially the pocket. Got water damage on my phone during a short time of rain. Most of the jacket will withstand the rain, but pockets are very susceptible to wetting out as well as the arms.

Overall, I like the jacket, but frustrated with some issues.

Great Lightweight Jacket

I have been able to wear my Rainrunner jacket a couple times and it is perfect. I even got caught in a snow storm on my last mile home and it kept me warm and dry! I can wear a small or medium in a lot of jackets and tops but I liked the fit of the small. If I was going to layer heavy layers underneath I would perhaps choose a medium? I am tall and slender.

Solid layer

This jacket is great, I’ve never purchased a rain jacket specific for running before and I like the hood and the vents on my Janji Rainrunner. The only thing I would ask for is additional reflective detail for better visibility. Overall happy with it. I usually wear a size 6 in shirts because I’m between a small and a medium in tops usually. I ordered a medium and it fits well with room for layering underneath.
