This thing weighs close to 8 pounds! Just walking around the block and 25° weather you’ll work up a sweat! You could pass out drunk on the north pole at night and be just fine! So either collectible or you’re going on an arctic expedition! Make is Southern athletic Co. Number is MIL Dash J – 6279F but I search for one for a long time and this was the best I found. But I got too much junk!
