The Marmot Men's Echo Featherless Jacket is a lightweight synthetic insulated jacket designed as a moisture-tolerant alternative to traditional down. It features Thinsulate insulation that mimics the warmth of 700-fill down while retaining its loft and insulating properties even when wet, making it ideal for damp environments and high-output winter sports.

The jacket is constructed with Econyl, a 30-denier recycled nylon shell that provides lightweight abrasion resistance while reducing environmental impact. It includes two zippered hand pockets, a drawcord hem to seal out cold and adjust fit, and weighs approximately 1 lb 1 oz with a hip-length cut. The regular fit allows comfortable layering with base layers or sweaters underneath.

Designed for hiking, camping, skiing, snowboarding, and casual wear, the Echo Featherless Jacket is lightweight and packable, making it easy to stow in a daypack. It is backed by Marmot's lifetime manufacturer warranty.
