Stay cool and comfortable in Patagonia's premium Merino base layer
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 sustainably sourced from the grasslands of Patagonia. We slow wash it for softness and shrink-resistance without the use of chlorine.
For our Merino Wool Baselayers we blend merino wool with all-recycled polyester for increased durability, improved wicking and faster dry times. The resulting garment provides higher performance in the field, is less fussy to care for and remains exceptionally soft against the skin, naturally odor resistant and machine washable. Our merino baselayer fabrics are bluesign® approved.

Patagonia has worked with bluesign® technologies since 2000 to evaluate and reduce resource consumption in our materials supply chain, and to assist us with managing the chemicals, dyes and finishes used in the process. bluesign technologies, based in Switzerland, works at each step in the textile supply chain to approve chemicals, processes, materials, and products that are safe for the environment, safe for workers, and safe for the end customers.
In 2007, Patagonia became the first brand to officially join the network of bluesign system partners.
Any fabric you see that’s bluesign approved offers the highest level of consumer safety by employing methods and materials in their manufacture that conserve resources and minimize impacts on people and the environment.
