Go ahead and do all the rain dances you can think of, but they probably won't stop the clouds from rolling in and opening up. The best you can do is pull on the Mammut Kira Women's Jacket, which is an exceptionally light and stowable rain jacket designed for hiking and backpacking. The polyester body fabric of the Kira is laminated to a 2. 5L Gore Tex waterproof and breathable membrane to keep you dry, but the shoulders, hood, and upper arms feature three layer construction instead, which offers superior waterproofing and durability in high wear and high exposure areas. The combination makes the Kira extremely waterproof while keeping weight and bulk down, so you can pack it easily and move comfortably when you're wearing it. The Kira has all the smaller features you'd expect to find in a bomber rain jacket, like fully taped seams to ensure weather protection and two way underarm zips to cool you off if you're hiking in warm rains or humid conditions. Even the front pockets are waterproof to protect your phone, snacks, and maps. The hood is fully adjustable, the soft inner collar protects your chin, and the hook and loop closures on the pre shaped sleeves fit snugly over gloves and keep water from sneaking up your arms.
