Satisfy Pertex® 3L Rain Cap — When the Sky Crashes, the Mind Stays Clear.

The Satisfy Pertex® 3L Rain Cap is built for focus when the weather turns. Shaped from Pertex® Shield Air — a three-layer recycled nano-ripstop developed in Japan — it keeps wet conditions out whilst letting air circulate freely through an electrospun membrane of microscopic pores. Seam-taped construction ensures full waterproof integrity, a PFC-free DWR finish sheds persistent drizzle, and a back adjustable bungee means it pulls on in seconds or packs down into a pocket when conditions clear.

 

 

Pertex® Shield Air 3L Construction

Pertex® Shield Air is a Japanese-developed nano-ripstop engineered for movement through weather. Its electrospun membrane forms an open network of microscopic pores — impermeable to wet conditions yet permeable to air and vapour — delivering durably water-resistant performance at 14,000mm hydrostatic head alongside exceptional breathability at 20,000g/m²/24h MVTR. Lightweight, tear-resistant and mechanically stretchable, it adapts to intensity and terrain without losing form across sustained efforts in challenging conditions.

 

 

Built for the Elements

A flexible brim deflects rain without limiting vision, whilst the low-profile fit integrates seamlessly with hoods and shells for layered wet-weather running. Stealth-reflective detailing and a ©Satisfy logo catch light in low-visibility conditions without disrupting the clean aesthetic. The exterior detachable care label eliminates any friction against the skin — nothing inside that shouldn't be there.

Is the Pertex® 3L Rain Cap Right for You?

For runners who don't stop when the weather does. The Pertex® Shield Air membrane handles persistent rain and wind whilst breathing hard enough to keep pace with sustained effort, the seam-taped construction leaves no weak points, and the flexible brim keeps vision clear when conditions close in. It packs down small enough to carry on any run and pulls on fast enough to use when you actually need it. For anyone who runs through all weather rather than waiting for it to pass — this is the cap for that.
