  • Superfine micron: 17.9–18.4 for softness that doesn’t itch
  • Midweight warmth with zero bulk
  • Breathable, moisture-wicking and naturally odour-resistant
  • Regulates body temperature in cold or fluctuating conditions
  • Moves with you – stretch and recovery built in
  • Ideal as a standalone or cold-weather base layer
  • Designed in New Zealand, made in China or Fiji
  • Easy care – machine washable on wool cycle

Description

For the colder months—or for those who simply run cold—the Midweight OG is your merino MVP. At 230gsm, it delivers a little more insulation than our standard OG, without compromising on breathability or comfort.

Soft, itch-free and naturally temperature-regulating, this long sleeve adapts to your environment and activity. From winter trail runs and backcountry hikes to layering under a jacket for the daily commute, it’s built to perform and made to last.

If you’re after a one-and-done merino top for cooler conditions, this is it. Same cut, same trusted fit—just a little more muscle.


Fabric & Care

  • Fabric: 100% Merino Wool, 230gsm
  • Micron: 17.9–18.4
  • Care: Machine wash cold on wool/delicate cycle with wool detergent. Lay flat or air dry.
  • Origin: Made in China or Fiji using NZ merino
