The Union Suit is a classic cold-weather base layer that’s been keeping outdoorsmen warm since 1868—and it’s just as essential for hunters today. Made with a drawstring waist for a secure fit, plastic buttons on the top half, and flat snaps on the bottom for easy use, this one-piece design locks in heat and provides full-body warmth for long, cold days in the woods or at camp. A timeless piece of hunting gear built for serious cold-weather comfort.
