Sierra Designs Women's Isotope Pants:
The featherweight-but-waterproof-breathable Women's Isotope Pant to accompany the Sierra Designs jacket, the Isotope. Fourteen-inch ankle zippers offer Velcro closures. The elastic waist has an adjustable drawcord hem to accommodate layers and facilitate on-off. The Isotope Pant has a performance fit, making sure they won't flap in the wind or bunch up when running or cycling. We use a slightly heavier nylon ripstop than the jacket, ensuring long life and proper function in these waterproof-breathable pants. Weights in ounces:
