The Marmot Men's Echo Featherless Insulated Jacket offers warmth without weight, combining the feel and performance of natural down with the benefits of synthetic insulation. Constructed from recycled 30-denier nylon fishnet fabric, this jacket features 3M Thinsulate Featherless Insulation with 700 fill power equivalent that eliminates common allergens associated with traditional down while maintaining insulating properties even when wet from perspiration or outdoor conditions.

Key features include zippered hand pockets for secure storage, elastic-bound cuffs that provide a snug fit to seal out cold air, and an adjustable drawcord hem accessible from the side for customizable coverage. The jacket utilizes 3D WarmCube technology that provides wind resistance while maintaining breathability. At 27.5 inches center back length and weighing just 1 pound 1 ounce, this packable jacket can be turned inside out and stuffed into its own pocket for convenient transport. Available in multiple colors including Black, Arctic Navy, Steel Onyx, and Rosin Green with regular fit sizing from Small to XXL.
