Game-Changing Woolly Underwear Picks For Women Worth Adding to Your Drawer

Underwear doesn’t often get the spotlight it deserves, but it plays a huge role in how you feel throughout the day. It should work with your body, not against it, breathable, smooth, and so comfortable you forget it’s even there. That’s where merino wool steps in, and Woolly Clothing has been catching attention for all the right reasons.

Woolly Clothing has built a collection around simple but thoughtful design using one of the most versatile natural fibers out there. Unlike heavy, itchy wools of the past, merino is soft, light, and gentle on the skin. It naturally adjusts to body temperature and resists odor, making it an excellent base layer for everything from workouts to lounging and daily commutes. Their women’s underwear lineup hits all the right notes, minimalist in appearance, but performance-forward in every way.

Top 10 Women’s Merino Underwear by Woolly Clothing

Before we get into the individual picks, it’s worth looking at what Woolly Clothing includes across the board. Whether you’re buying a single pair or stocking up, the same standards apply and they’re surprisingly generous.

All pieces are designed in Seattle, crafted using Responsible Wool Certified merino, and shipped in plastic-free packaging. That attention to sustainability is echoed in their return policy too. If your Woolly underwear doesn’t meet expectations within a year, they’ll replace it. That’s not a common promise and it speaks volumes.

You also get easy returns, free exchanges, and two-day standard shipping as part of the experience. Orders over $35 qualify for flexible payments with Shop Pay, making it easy to try a few styles without committing all at once.  Now let’s dive into the top ten picks from Woolly Clothing’s women’s underwear collection.
