Don't let the light weight fool you - the Drake Men's MST Synthetic Down Pack Vest is incredibly warm and versatile. The vest is packable and zips into its own vertical chest pocket, making it the perfect size for stowing in a blind bag, ATV, or boat. Featuring a traditional, horizontal baffle design, durable and abrasion-resistant, matte-finish shell material, and drawcord adjustable waist, this jacket 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. The average weight is just 9.2 ounces (size Large). When packed, it measures 8" W x 7" H x 4" D and can be compressed even smaller. The stuff pocket has a carabiner loop for clipping the jacket to a backpack.
