Considerations & Trade-offs

  • The 250g interlock fabric is a warm option, so it may be more than you want for milder conditions or higher-output activity.
  • The fit includes 5% spandex and an elastic waistband, which supports comfort and mobility but may not suit hunters who prefer a more structured feel.
  • Merino wool is naturally moisture-wicking and antimicrobial, but it still needs to be matched carefully to the rest of your layering system for changing conditions.
  • Flatlock seams are designed for next-to-skin comfort, but this is still a base layer bottom rather than an outer layer, so it’s intended to work under other clothing.
