If it's equally a shirt and a jacket, then the only term that works is…Shacket! The Browning® Hell's Canyon Contact Shacket a rugged polyester hunting Jacket with a soft flannel lining and warm PrimaLoft® insulation quilted into the chest and back. It's thicker and warmer than a flannel shirt, but less bulky than a jacket. So you can wear it under your hunting gear when it's super-cold, or on its own when you're prepping your stand or sitting around deer camp. It's basically whatever you need it to be.
