Run in silence and warmth with the Nathan Stealth Jacket 2.0. Banish the swishy fabric noise as you run—the UltraAire™ fabric is noise free, lightweight, quick drying and stretchy. Plus, it is wind and water resistant with a DWR finish to repel water. Throw it in your hydration vest or gym bag, this jacket compactly packs into its own pocket and is so lightweight that it is easy to carry, so you can deploy it the moment the weather turns. This jacket is made for running with a ventilated back to allow heat to escape, attached hood with drawstring and thumbholes for layering. You can run as hard as you want without hearing a peep from the Nathan Stealth Jacket 2.0.
