The Marmot PreCip Eco Jacket has become a fan favorite for a reason, boasting incredibly breathable waterproofing for trekking in wet weather. The NanoPro waterproof membrane blocks wind and water while allowing air to circulate, so whether we're pushing towards an alpine summit or walking in swampy forests, we stay cool on the move. The sealed seams keep moisture from sneaking in to our baselayers, and the adjustable hem and cuffs create a barrier from sideways blowing rain. In warm weather, we can unzip the underarm vents to allow hot air to escape, and the adjustable hood stows away into the collar for those moments when the sun breaks through the clouds, and we're rewarded with stunning views.
