Care

Wash: Pop your Woolly in the machine on a cold cycle with similar colors. But be careful—fine merino fibers can snag on zippers, buckles, and Velcro. Avoid washing with jeans, jackets, backpacks, or any harsh fabrics.

Dry: Tumble dry on low or go au naturel and hang it up to dry.

Avoid Bleach: Skip the bleach—it’s not a friend to wool fibers.

No Iron Needed

Pilling: Wool may pill over time, but turning your garments inside out before washing can help slow this down.

Air Dry Option: For the air dry lovers out there, lay your wet Woolly on a towel, roll it up like a burrito to gently squeeze out extra moisture, then hang it up for a breezy air dry!

    Favorite underwear

    I bought a thong from the top 5 wool underwear companies so I could compare and these were by far my favorite. They arrived the soonest, are the most comfortable, are breathable, and are super cute.

    Never smell again

    its a good standard thong. I would say to size down instead of up, its stretchy but super soft. I work in the backcountry and can no longer wear alternate undies, as these dont get sweaty or stinky.
