It's always nice to have a reliable puffy in the fall and winter, and it's even nicer when that puffy is made with an innovative and eco-friendly construction. That's exactly what you'll be getting with the new Mountain Khakis Triple Direct Jacket, which gets it warmth from a new insulation that they're calling SeaWool. The reason for its nautical name comes from the material makeup, which includes post-consumer recycled polyester and crushed oyster shells. Taking advantage of an often discarded material, SeaWool combines oyster shells with polyester to create an insulating fiber that behaves much in the same way as wool. Just like wool, SeaWool insulates well, dries quickly, resists odor, remains relatively lightweight, and offers anti-static performance, so you can stay warm and comfortable in chilly weather while knowing you're using as few new materials as possible in your jacket. The tough outer shell resists water to keep you dry in snowy conditions, and the metal-snap storm flap ensures that cold winds won't creep in through the zipper.
