NRS Expedition Union Suit


There's a time and a place for a onesie, and we believe that time and place is by the fire on a cold fall night or on a boat in the middle of winter. The NRS Expedition Union Suit delivers ultimate insulation for those cold-water, chilly-air days.

Product info


  • Polartec® Power Stretch Pro® fleece, the industry leader, provides outstanding warmth, wicking and comfort.
  • Shed your outer layers and gather wood at camp with ease, the durable, smooth exterior resists pilling and abrasion.
  • 4-way stretch fabric and paddling-specific cut lines allow for a snug and pleasant fit without sacrificing mobility.
  • Form-fitting design allows layering without the added bulk of other mid-weight thermals.
  • "Touch points" on the fabric inner surface draw off the sweat. Then it's quickly wicked to the outer surface where it spreads and evaporates rapidly, to keep you warm and comfortable.
  • Double-stitched seams will withstand years of use and abuse.
  • Double-pull zipper for easy entry and convenient relief.
