Exceptionally soft, naturally breathable and warm even when wet, merino wool regulates your body temperature, has a great warmth-to-weight ratio, naturally controls odor and stretches as you move. Our merino wool is sourced from the grasslands of Patagonia. We slow-wash it for softness and shrink resistance without the use of chlorine, a chemical that can produce harmful toxins depending on how it is used. We blend merino wool with Capilene® recycled polyester for durability, wicking and faster dry times that are unmatched by 100% merino clothing.

Over the years, we’ve tried a variety of merino fabrications, including the use of 100% merino wool in our Baselayer line. Despite a high level of comfort in the finished garments, the durability of 100% merino garments did not meet our quality standards. This forced us to ask if we were living up to our mission to build the highest-quality products and do no unnecessary harm (we prefer to create products that are better made because building products that can’t take a beating requires continued production of new products). By using a blend of recycled polyester and merino wool in our Merino baselayers, we dramatically increased durability.

There are other benefits, too. Our wool/polyester blend boosts the wicking function of the fabric and reduces overall dry times. The resulting garment provides higher performance in the field; remains exceptionally soft against the skin; and is less fussy to care for, naturally odor-resistant and machine washable.

We make our Merino baselayers in three weights for different levels of insulation and activity. We’ve also created a new class of merino baselayer with exceptional breathability and warmth for its weight: Merino Air™. Merino Daily is another new offering that provides the natural comfort and odor-fighting properties of merino in a regular fit for everyday activity and wear.

Merino Thermal Weight is our warmest Merino baselayer. The jersey knit is insulating without being bulky and is naturally odor-resistant. The fabric is bluesign® approved, ensuring the highest level of consumer safety by employing methods and materials in its manufacture that conserve resources and minimize impacts on people and the environment.
