Sierra Designs Isotope Jacket - Women's
The Sierra Designs Women's Isotope Jacket lightens your load in the backcountry with a windproof, water-resistant outerlayer that practically disappears when not in use. Sierra Designs Nanolite nylon ripstop fabric is coated with a microporous membrane that allows the Isotope Jacket to breathe while keeping you dry. The fully taped seams, zippered hand pockets, drawstring hem and adjustable hood seem like standard features, especially for Sierra Designs, but you might not expect them on a jacket that weighs a scant 4.8 ounces (size Medium) and stuffs into its own pocket.
Bottom Line: The Isotope Jacket puts featherweight, waterproof protection in the palm of your hand.
