The Insulayer Originals 2-Layer Long Underwear Pant, from performance apparel manufacturer Duofold, is great for a wide variety of outdoor activities, including trekking, camping and skiing. The comfortable Merino wool blend outer layer and an extremely soft 100% cotton inner layer form a 2 layer thermal barrier that traps air and keeps you warm in very cold weather. A mid-weight pant, this Duofold style has flat seams to prevent chafing and a fit that remains close to the body. The Duofold label is sewn at the front center of the comfortable elastic waistband.

  • 6.3-oz. fabric has two non-bulky layers. Outer layer contains Merino wool for natural insulation. Inner layer is pure cotton, for softness next to your skin. Together, both layers trap air to create a warm thermal barrier.
  • Tag-free elastic waist wicks moisture for added comfort.
  • Ankle length, with ribbed bottom cuffs and non-chafe flat-locked seams.
  • Close-to-body fit.
  • Convenient front fly.
