Product details

The M Mer 125 ZoneKnit™ Short Sleeve Shirt from Icebreaker is a highly functional top designed specifically for active individuals. Made from a lightweight blend of merino wool and TENCEL™ Lyocell, it offers excellent breathability and ensures a comfortable wearing experience during intense activities. The innovative ZoneKnit™ technology features strategically placed eyelet mesh inserts to optimize ventilation exactly where it is needed most. The gusset construction and raglan sleeves allow for unrestricted freedom of movement, while the flatlock seams minimize friction and provide a soft feel against the skin. Additionally, the Cool-Lite™ material naturally regulates the body's microclimate, ensuring that the shirt dries quickly and remains lightweight. This shirt is ideal for outdoor activities and offers a sustainable alternative to traditional performance shirts.

  • ZoneKnit™ technology for targeted ventilation
  • Cool-Lite™ material for optimal temperature regulation
  • Raglan sleeves and gusset construction for freedom of movement
  • Flatlock seams reduce friction and enhance comfort.
