The Rainrunner Pack Jacket is a 2.5-layer laminated shell built for running in serious weather, combining a 20,000mm waterproof rating with 20,000g/m²/24hr breathability and fully taped seams to keep moisture out without trapping heat. A 360° panel venting system around the core releases heat where it matters most, while the lightweight ripstop fabric stays windproof, durable, and fast-drying. The streamlined, ergonomic silhouette layers cleanly over midlayers without restricting stride, and a scuba hood with 180° visibility and bungee toggle adjustability keeps protection dialed in changing conditions. When the weather clears, the jacket stows into its own left-hand pocket with an integrated elastic carry strap.
