Merino Wool Care Guide


The Feel of Merino Wool

Merino wool stands out for its exceptionally soft texture and superior breathability. Unlike traditional wool, it feels fine and smooth against the skin, making it ideal for base layers, activewear, and refined knits. Its natural temperature regulation and moisture-wicking qualities make it a go-to for performance and comfort.

What Is Merino Wool?

Merino wool comes from Merino sheep, known for their fine, long fibers that produce a softer and lighter wool compared to standard varieties. It retains all the benefits of wool—insulation, breathability, and odor resistance—but with less itchiness and better elasticity.

Origins and Usage

Merino sheep originated in Spain and are now farmed globally. Merino wool’s blend of softness and durability has made it popular in technical outdoor apparel, luxury knitwear, and everyday garments that demand comfort.

Merino Wool Blends and Variants

Daily Care for Merino Wool

Keep Merino wool fresh by:

  • Airing out after use to reduce odors

Home dry cleaning also preserves the integrity of Merino wool garments.
