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+
