Life in the mountains or on the flats is unpredictable, making a lightweight stashable rain jacket a necessity. The Rivulet is a 2.5 layer DWR-treated Nylon performance shell with taped seams that offers waterproof protection and excellent breathability in a light but bomber package that's perfect for quick moving storms. Welded inside the jacket, you will find a pocket for your phone, or any of your water-sensitive valuables. The front of the jacket includes two zippered pockets for your hands and an oversized chest pocket for anything you need quick access to. No need to worry about a little precipitation ending your outing when you have the Rivulet on hand.
