The Women's Marmot Featherless Component Jacket provides versatile yet practical protection against windy, cold, and wet weather. The Featherless Component Jacket is basically three jackets in one.

Full of warmth, no feathers needed. The zip-in inner layer of the Women's Featherless Component Jacket utilizes a revolutionary additional in the outwear world: 3M Thinsulate Featherless insulation, a loose-fill synthetic insulation that generates warmth like traditional down but maintains twice the loft when wet, giving it a leg up in damp conditions. It gets better: this three-in-one jacket boasts a Marmot MemBrain waterproof breathable two-layer outer fabric that is seam-taped to ensure excellent weather protection. The ability to adapt to the elements and your needs make the Women's Marmot Featherless Component Jacket a fundamental piece for serious yet practical weather protection.
