Introducing a totally waterproof, seam-sealed yet fully breathable rain jacket with 360o core venting—where it’s needed most. Strategically designed for running by prioritizing lightweight yet robust weather protection and high-output movement, this jacket is streamlined to reduce unnecessary bulk or components. The unique panel venting system acts as an air-intake on the chest while the back vents release heat from the core to prevent the swampy overheating of many waterproof layers. Articulated sleeves, cuffs and hood stay in place in motion without the need for additional adjustment of bungees or pulls for an unfussy stride.

No fuss, all rain running glory.

  • 2.5L waterproof laminated, breathable shell for rain protection + comfort while running

  • Ultra-light stretch ripstop fabric is fully wind-blocking, durable + allows total range of movement

  • 360º panel venting around the core for added breathability

  • Signature R.A.P.I.D. (Racerback Air Panel Integrated Design) vent system to release heat + moisture, preventing swampy overheating
  • Sleek, ergonomic running silhouette designed to easily layer on top of mid-layers while reducing unnecessary components that can get in the way of efficient strides

  • Self-stowing pocket with integrated nylon hanging strap for travel convenience

  • YKK AquaGuard® water repellent zippers in high-contrast agave color

The 360o panel venting wraps the body at the core (even under the armpits) to intake air and release heat where it's generated the most. This helps to regulate temp + wick moisture from the inside of the jacket to prevent that swampy feeling of many seam-sealed waterproof layers. ⬅︎⬆︎

Great Rain Jacket

This jacket is amazing. It ventelates really well...the vent design is super unique. It also lives up to its waterproof name!

My one complaint is that it’s a little tight around the armpits. I’m 6’1” and I got a large. If I were to get an XL, I think it would be too big.

Loving it

I’ve had several running jackets from other companies in the past, and was happy with all them.
But this one is next level. Love the 360 vents, very waterproof, great fit, light, easy to store/pack and looks good enough to wear for generally daily use not just running.
I will admit, I was hesitant to spend that much money at first, but it’s totally worth every penny.

Stood up to the challenge

I gave this jacket a real test in low 50's torrential rains for an hour of trail running. The jacket did a great job keeping me dry. When I wear a jacket I tend to overheat no matter the circumstances, but this jacket has great ventilation. I also made good use of the hood. It fit well over a cap. This jacket is the best I have found combining waterproof materials and good airflow.

Lightweight and Ventilated

This jacket is great! I've worn it on mild (50s/60s) rainy days over a t-shirt and colder (30s/40s) days over a long-sleeve. In both instances, I felt good - not too hot, not too cold. It's also very lightweight. I look forward to many more uses!

The perfect trail running shell!

I had long been looking for the lightest possible shell for trail running and I couldn't be happier with this remarkable jacket. I had always carried a Patagonia Houdini in my running vest in case things got ugly but that jacket is far from water proof. The materials on the Janji Rainrunner jacket are incredible. The fabric has stretch to it, it is unbelievably light, and it's actually waterproof! Took it on a run last night after our first snow of the season. The jacket breathes extremely well and the venting system is well thought out. Can't recommend this jacket enough!

All Janji is limited run!
