Don't let the light weight fool you - the MST Synthetic Down Pack Jacket is incredibly warm and versatile. The jacket is packable and zips into its vertical chest pocket, making it the perfect size for stowing in a blind bag, ATV, or boat. This jacket has a traditional, horizontal baffle design, durable, abrasion-resistant, matte-finish shell material, and a drawcord adjustable waist. It works equally well as an outer layer as it does a mid-weight, insulated layering garment. Synthetic down is ultralight, has uniform loft throughout the garment, and won't mat down like natural goose down.
