MEC Merino T3 Long Johns - Men's


See available base layer bottoms


Merino is a natural choice for base layers. It's soft, naturally anti-microbial, and has give and stretch. Worn next to the skin, it buffers temperature changes, so you don't feel instantly chilled when a wind springs up or the sun goes down. This heavy-weight thermal layer is breathable for strenuous pursuits like skinning up slopes, and feels soft against your skin when worn under layers.

  • Made of merino wool in an expedition weight fabric for cold-weather activities
  • Low-profile elastic waistband for easy, comfortable layering
  • 32in. inseam across all sizes
