At 10.9 ounces, the Brooks Down Sweater is the definition of ultralight, highly packable backcountry insulation. Built with 100 grams of DWR-treated, 800-fill power, 37.5-DownTek, the Brooks provides advanced, active insulation that fights off moisture to keep both you and your down insulation warm, dry, and comfortable. When you're miles into the backcountry, weight is key, but not at the expense of your insulation that keeps you warm and protected. With that at the forefront of our minds, the Brooks was designed using 50% more down than its closest competitor to be the lightest weight possible while ensuring best-in-class warmth. The Brooks Down Sweater features a drop-tail hem for critical coverage when glassing, and an ultralight Turret hood design that can be operated with one hand to lock in heat while maintaining full field-of-view. Whether you are packing into the high Tundra for caribou in August or climbing southwestern Sky Islands for Coues deer in January, the Brooks Down Sweater is the trusted choice to guarantee your warmth while maintaining durability in the field. The Brooks Down Sweater is engineered to fit close to the body for insulating purposes. Please be aware of this and size up one size if you feel you are between sizes. .product-type-data{display:none;}
