NRS Expedition Weight Union Suit Men’s

From the patent of the first union suit in 1868, the one-piece thermal layer has been known for warmth, comfort and freedom of movement. While that part hasn’t changed, upgrades in design and materials, like the thick plush fleece of our Expedition Weight Union Suit bring a modern, high-performance take on a classic.

• High-stretch poly/spandex fleece delivers outstanding warmth and breathability.
• Designed to sustain many seasons of wear, the 4-way stretch fabric holds its original shape while anti-pill properties guarantee the fleece stays soft and cozy.
• YKK®, double-pull, front entry zipper with an interior fabric flap for against-the-skin comfort.
• Seam placement avoids high-friction zones, enhancing athletic performance and layering comfort.
• Stirrups keep legs from riding up and gasket-friendly cuffs create an easier layering experience under a dry suit.
• Form-fitting for athletic comfort and easy layering.
• UPF 50+
