Overview

Built for layering in cool conditions, this crewneck baselayer pairs merino wool with Acclimate Dry fibers to help hold warmth while moving moisture away from the skin. The midweight blend and 4-way stretch are suited to active days in the field, where comfort and mobility matter under outer layers. A relaxed fit adds a less restrictive feel, while the odor-blocking yarns are a practical touch for extended wear.

Pros

  • Naturally insulating merino wool blend provides midweight warmth for cooler conditions.
  • Acclimate Dry fibers help move moisture away from the skin.
  • Odor-blocking yarns support longer wear between washes.
  • 4-way stretch and spandex improve comfort and mobility.
  • Relaxed fit allows easy layering under outerwear.

Considerations & Trade-offs

  • Midweight warmth is built in, so this layer is better suited to cool conditions than to high-output use in milder weather.
  • The relaxed fit and stretch construction favor comfort and mobility, but they may feel less close-fitting than a more compression-style baselayer.
  • The fabric blend includes polyester, merino wool, and spandex, so it is not a pure merino layer for those specifically seeking that construction.
