  • Breathable, moisture-wicking and naturally odour-resistant
  • Regulates body temperature in cold or fluctuating conditions

  • 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

Great quality

Great quality… not scratchy at all… men’s colour options are better than women’s plus they are longer in the body and sleeves… perfect for me

Merino long sleeve

This top is so good for my husband, light but so warm, great length for a taller person - he is so happy with it.

Awesome shirt for Fiorland hikes

Perfect shirt for Fiordland hikes: Long sleeve keeps the sandflies at bay. And the 190 gsm weight is perfect for almost any temperature.
