The magic is in the fabric's controlled air permeability. By using advanced, tightly woven textiles like Pertex® Quantum, these jackets block the wind while allowing just enough air to pass through to offer exceptional breathability, preventing the clamminess associated with less specialised layers. This makes it the perfect windproof running jacket for cool, blustery days.
Every feature is optimised for minimalism and speed. Expect an athletic fit, elasticated cuffs, and a design so light and packable that the entire jacket often disappears into its chest pocket. Models like the iconic Patagonia Houdini or a technical Rab windproof jacket are staples for climbers, runners, and cyclists because they provide crucial protection with virtually no weight penalty. When you need to move fast and stay protected from the wind, this is the layer you'll reach for every time.
