Marmot Heat Technology

Polartec® Power Dry®

What is it ?

Polartec® Power Dry® fabrics are designed to keep your skin dry when you sweat. Ideal for runners, skiers, and adventure travelers, all fabrics feature a patented bi-component knit construction that uses different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly.

This is why Marmot has chosen to use Power Dry® fabrics for our new ThermalClime Sport and Pro baselayer series.

How does it work?

"Touch points" on the fabric inner surface draw moisture. Sweat is wicked off the skin to the outside of the fabric where it spreads rapidly for evaporation. Polartec® Power Dry® fabrics move at least 30% more moisture away from the skin than single-component fabrics.

When the sweat reaches the outside of the fabric, it spreads out on the outer surface of the fabric, enabling it to dry at least 2 times faster than cotton.

  • Superior wicking action
  • Keeps your skin dry when you sweat
