2.5l waterproof

360 venting



Taped seams

We strategically designed the Rainrunner for high-output performance by reducing unnecessary bulk or components and prioritizing lightweight weather protection. The unique panel venting system acts as an air-intake on the chest while the vents under the arm and across the back release heat from the core to prevent that 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. Three zippered pockets — including a packable left side pocket with elastic carry strap — and a new snap closure to stow the hood make the Rainrunner an essential layer to bring wherever you go in case of variable conditions.

Unparalleled venting

The Rainrunner is our first outerwear to use a PFC-free water repellent finish on the fabric, which unlike standard DWR's, is not made with harmful PFC's and therefore will not release any perfluorinated chemicals into the environment from wear or washing.

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.

Excelente chamarra

Es una chamarra ligera repelente al agua, la recomiendo mucho ya que las especificaciones indican lo que realmente es la marca. Calidad.

Amazing performance!

This is the best jacket I've even owned in my 30 years of running! I have had this out on multiple runs in the rain and stayed warm in dry. Temps ranged from low 40's to low 30s. Worth every penny!

Awesome Jacket!

I love this jacket. I admit that I debated buying it for a year- it's a little pricey and I wasn't thrilled with last year's black. I kept searching all the lightweight, water proof jackets for running and hiking. I kept coming back to Janji, and when they came out with colors bought the orangish one for myself. I wear it for EVERYTHING-- running in the rain, mountain biking, cross country skiing, hiking. It's light, it's packable, it's waterproof, and it doesn't make that squishy nylon sound most jackets make. I bought this one for my husband- it just arrived yesterday and he can't wait to try it today. I know he'll love it.


I know.. it's expensive. But it is worth it.

For someone like myself who lives in a cold rainy city, this jacket does it's job in keeping me dry. And the slits around the chest provide a good amount of ventilation. Feom the photos and first examining the jacket, I thought that it would not retain any warmth due to the number of slits, but I realize that this isn't the case. It is extremely lightweight. The pockets are plentiful. A+

Only gripe comes in the strap found in the pocket used to put around arm when stuffed away. It seems to be losing its elasticity after only a few uses. Maybe next jacket will come with two straps for better hold?

Light weight and comfortable

Love my new Rainrunner jacket! It's incredibly light weight and perfect for running in any weather.
