Best Use: Whitetail - Frigid Conditions As the first of its kind, the Super Down Haven combines an innovative down-proof, windproof, and ultra-quiet knit fleece with our legendary Quixdown insulation, making it the warmest and lightest late-season whitetail hunting jacket on the market. Down insulation provides unmatched warmth-to-weight ratio, but it was previousely unsuitable for whitetail hunting due to the loud fabrics—until now.Haven’s outer layer fleece features a SynthaCell® closed-cell foam inner coating that makes it windproof and down-proof, while locking in body heat. Its box-baffle construction houses the 850+ fill power Quixdown insulation, creating an even layer of warmth around the body.We leverage our 3DeFX+ synthetic insulation for a streamlined fit in the lower leg, whether worn over or tucked into your boots. The seat of the bib utilizes layers of both down and 3DeFX+ for the perfect amount of warmth, and compression resistance needed for sitting on a frozen treestand.Built with a whitetail hunting specific feature set, the Haven includes removable suspenders for easy care, ultra-warm hand pockets, an adjustable waist cinch to lock in heat, and full side zippers for easy on and off.
