Show Description

Baselayers that are so versatile, they go under anything in the winter, then work on their own in the summer. Wicking fabric dries really fast, and it’s equipped with Polygiene antimicrobial technology that keeps it smelling fresher for longer. UPF 40 sun protection means you’re good to go when the sun comes out.

  • Made of moisture-wicking polyester and spandex to keep you dry and comfortable.
  • Flat seams don't chafe or add bulk, so they're good for layering.
  • Polygiene® antimicrobial treatment is great for days on the trail or traveling.
  • Fabric has a UPF 40 rating.
  • Interior name label so it won't get lost.
  • Coordinates with MEC Lightweight Baselayer Long John.
