Terramar MicroCool Tops

When the going gets hot, keep going with these MicroCool tops from Terramar. The company’s MicroCool system using a combination of yarn-based technologies to maximize comfort, wick moisture, dry quickly, and lower skin temperature when you’re on the trail. The four-way stretch fabric features strategically placed mesh panels for enhanced breathability, along with a 50+ UPF rating. Finally, the antimicrobial treatment means you can get an extra day (or two) out of your top when needed.

In each of Terramar’s MicroCool tops, the flat yarn creates a broader surface area to draw heat away from the body, while the embedded nano-mineral particles enhance heat absorption. Aqua channels transport moisture through the fabric to the outer layer, where it then spreads along the surface to cool the fabric down further. The result is a shirt that’s cool to the touch and provides an instant cooling sensation back to the skin.

For more than 40 years, Terramar has been dedicated to producing one thing: base layers. From thermal bottoms to merino crews—not to mention socks and underwear—the product line comes from a team of scientists, gear heads, and designers whose single-minded pursuit of the perfect base layer has led to no fewer than six patented technologies. Whether it’s the way the fabric fits or the way it neutralizes odors, these innovations have revolutionized the active lifestyle.
