Description

Our bestselling Aspect Merino Wool Base Layer is now available with a classic 1/4 zip at the front. The midweight Aspect top features an exclusive design that feels great next to your skin and keeps you warm, dry and comfortable. It also incorporates our (m)Force Technology to achieve industry-leading durability. This base layer top is designed for an active lifestyle—it's cut long to stay tucked in, it has discreet thumb holes to keep your sleeves in place, and it fits close to your body so it keeps you warm without any bulk. Pair it with the Aspect bottoms in full length or 3/4 length.

Product Features
  • All the benefits of Merino wool: resists odor, wicks moisture, protects from the sun, breathes well and regulates temperature
  • Natural and sustainable Merino wool reinforced with (m)Force Technology for increased durability, dry times and recovery
  • Versatile mid-weight base layer that's warm but not too warm
  • Flatlock seams
  • Backpack-friendly raglan construction
  • Discreet thumb loops keep sleeves in place when needed
  • Printed neck label
  • Removable care label
  • Long cut for layering that stays tucked in
Fabric Details
  • 84% Merino wool, 16% Nylon
  • Soft 180 GSM (m)Force Merino 18.5M wool
  • Size M weight: 8.3oz
