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.

    I absolutely love these. I finally have six pair now, and I think that might be good, but probably not. I will never wear another kind of underwear again.

    Oversized, tangles in wash - but epic odor control

    I def had to size way down. I usually get a medium, sometimes a small in underwear. I exchanged the small I ordered for an XS had some issues with the exchange but customer service worked it all out. The XS is still quite large because of the stretch, but it works. Once on I don’t even feel them. An excellent product bc there’s no body odor in the fabric after all day wear in the heat!! I absolutely love and will likely order many more in the future. Only other issue is that after washing, the waist band got a bit folded in on itself and wouldn’t lay flat under my leggings, but I was able to fix it with some effort. I may hand wash and lay flat to dry to avoid this in the future but a different design might prevent this.
