Fast-Wicking, Bacteria-Fighting & Breathable

Made from a blend of merino wool and brushed microfiber, Terramar’s Thermawool Bottoms are engineered to insulate in cold weather and breathe in warm weather. Combined with the company’s ClimaSense thermoregulation treatment—which inhibits bacterial growth, wicks and dries quickly, and adjusts to your body temperature—it’s a super-comfortable midweight layer for active adventures come rain, snow, or shine.

Note: At checkout, you’ll have your choice of the men's pants in Light Heather Gray or Smoke Heather (S-2XL), the men's tall pants (+ $4) in Smoke Heather (M–XXL), or the women's pants in Ink Heather or Smoke Heather (XS-XL).

About Terramar

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.
