After a few goes in the WoolCloud Full Zip Jacket you'll never want another traditional down or synthetic-puff jacket again. Why? Well, when down gets wet, it becomes a mushy, wet ball, and when synthetic fillers get wet and worn, they become increasingly compressed, providing less insulation and less bang for your buck. WoolCloud, however, is filled with a proprietary Montana-grown Merino Wool batting, which never loses its loft and insulation, and actually chemically becomes warmer as soon as it's introduced to water. That's right, the wetter it gets, the warmer. Lightweight and boasting a shell of 40 denier rip-stop polyester (water resistant), the WoolCloud Full Zip Jacket also features a paneled hood, two large hand pockets and a full zip front. The finished product: a versatile, warm, durable, breathable, tailored-fit jacket up to any foul weather task. Toss on an extra shell for when the rain starts going sideways, and you're guaranteed to stay warm and dry until the clouds part.
