Introducing Patagonia Merino Air Baselayer

Lightweight technical performance seamlessly knit with responsible sourcing.

Fine merino wool from our regenerative sheep grazing program in the Patagonia region is spun using a proprietary process that increases the yarn’s heat-trapping ability. It’s then blended with 100%-recycled Capilene polyester using innovative whole-garment seamless knitting that creates a lightweight, superbreathable, performance-fit baselayer perfect for high-output activity in cold conditions.
