What Our Customers are Saying

“
I really love the thong set! I haven’t had things as comfortable as these. I love wearing them. They are my new favorites. I bought more as soon as I tried them on. Highly recommend.

“
Can confirm, my most comfortable underwear ever. I wore it on a 27-hour journey from Europe back to Australia and they felt amazing the whole way. Cannot recommend enough.

“
The fit and feel of the merino wool is wonderful. They're lightweight, breathable and don't pinch in any areas and create those awful panty lines through your clothes. Love them!!

Au Natural x The Woolmark Company

Au Natural has partnered with The Woolmark Company to create "lace-inspired" Merino wool underwear.

The newest collection combines feminine colors with the game-changing benefits of Merino wool.

Au Natural is the first Woolmark-certified underwear in the United States. This means you can trust the quality of the product and the journey of the wool from the sheep’s coat to your top drawer.
