Best Merino Wool Clothing Brands

Why merino wool?

Regulates temperature

Merino fibers crimp at a microscopic level, trapping air to warm you and releasing heat when you run hot. Works from 30°F to 80°F.

Naturally odor-resistant

Wool's protein structure binds to odor molecules and holds them until washing. You can wear merino multiple days without it smelling.

Mulesing-free options exist

Look for ZQ Merino, Responsible Wool Standard, or GOTS certifications. The brands on this list disclose their sourcing.

Biodegradable fiber

Merino wool breaks down in soil in under a year. Compare that to polyester fleece, which sheds microplastics for centuries.
