Story
An ultralight windbreaker that packs into itself when not in use
The Packable Windshell is an ultralight, packable layer designed for runners who want serious performance without the bulk. Built from a durable micro-ripstop nylon that allows ample stretch, it delivers wind protection and light water resistance thanks to a durable water repellent (DWR) finish. Under the arms, mesh panels add breathability where you need it most, while an open back vent lets excess heat escape. And when the weather clears, the entire shell packs neatly into its own left pocket using a two-way zipper—making it easy to stash or deploy mid-run. The result is a windshell that keeps you protected from the elements while staying light, silent, and fast.
