Regardless of the sunny forecast, we know how quickly things can change so we pack along the Marmot PreCip Eco Pro Jacket to stay dry when conditions shift. The light, breezy build keeps internal condensation low, while the sky's steady stream glances off the 20K membrane. The jacket is feather-light and easily packable while unwavering on performance so we can withstand sudden downpours from passing storm, and the zippered underarm vents and breathable material help keep us cool as we work up a sweat.
