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.



Waterproof protection
2.5L laminated shell with a PFC-free water repellency provides an environmentally friendly rain shedding finish

Taped seams
10K/10K waterproof + breathability (W/P: 10,000mm, M/P: 10,000gm/m2/24hrs) fabric rating with fully taped seams

Stretch ripstop fabric
Lightweight stretch ripstop fabric is wind-blocking, durable + allows total range of movement

Unparalleled venting
360º panel venting around the core for added breathability + heat release where it's needed the most

Streamlined fit
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

Secure pockets
Two zippered hand pockets with thin nylon pulls for easy open/close plus a secure internal chest pocket

Pack it up
Self-stowing pocket with integrated elastic carry strap for travel convenience

Super smooth zippers
YKK Vislon® AquaGuard® water repellent front zipper with a nylon pull

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.
