BENEFITS

Breathable

Transports moisture away from the skin, meaning less sweat on your body. Helps keep your most private parts cool when it gets hot.

Soft

Softer than cashmere and smoother than silk, so no uncomfortable itching or scratching.

Odor Resistant

Absorbs odor molecules caused by sweat, meaning you can wear your undies longer without worrying about any unpleasant smells.

Elastic

Moves with your body then returns to its original shape after washing, meaning your undies stretch to fit your unique size.

Durable

Naturally durable and high-quality means no guilt keeping undies for a year+.

Sustainable

Merino wool fiber is 100% natural, renewable, and biodegradable (good for the planet).

What Our Customers are Saying

“
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!!

“
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.

“
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.

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.
