Protect yourself from precipitation while releasing your perspiration in the breathable, waterproof Marmot Women's PreCip Jacket. The PreCip is 43% more breathable than last year, while offering solid 10K rated waterproof protection. Throw on this comfortable shell when heading out on the trail in wet weather, and its microporous NanoPro membrane with microscopic, densely packed pores and a DWR durable water repellent finish will go to work keeping rain drops out while letting perspiration through. The DriClime mesh chin guard prevents moisture buildup from your warm, moist breath and dripping sweat moving it quickly away from your skin and drying quickly. Fully taped seams ensure rain doesn't sneak through the cracks, and you can batten down against the elements by pulling in the hood, hem, and cuffs. For additional ventilation if you start getting steamy huffing up a hill, unzip the underarm vents. If the weather clears up, roll up the hood and stuff it in the collar to keep it out of the way of your backpack. Or stuff the whole jacket into one of the zippered hand pockets that double as stuff sacks, and pop it in your backpack. It weighs a mere 11. 4 ounces, so you'll hardly notice it's there.
