Merino Wool Base Layers for Every Season
Shop 100% merino wool base layers built for year-round comfort — long sleeve thermal tops, base layer pants and matching sets for men and women. Merino wool is naturally moisture-wicking, odor-resistant and temperature-regulating, keeping you warm in winter layers and cool on summer trails without the clammy feel of synthetics.
Choose your warmth: lightweight 165 gsm merino for travel, running and everyday wear, or midweight 250 gsm merino for skiing, cold-weather hiking and winter commutes. Every piece ships free in the US over $49.99 and is backed by a 1-year warranty.
