SOFTER THAN COTTON
This wool isn’t like your typical itchy sweater. We only use superfine (16.5 micron) Merino wool, resulting in a luxuriously silky soft feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.
NATURAL AIRFLOW
With Merino wool, your body heat can pass through the space between our woven superfine fibers, regulating your body temperature and keeping you cool & comfortable.
Cozy Softness
Modern spinning technology has made Merino wool the softest, most luxurious of all wool types. Perfect against your skin, the fibers will never itch or irritate, outclassing synthetic fibers.
EASY CARE
You won’t have to wash this bra much at all. However, when it comes time for a refresh, simply add it to your load at the cold temperature gentle setting and then lay flat to dry in shade.
ABOUT OUR WOOL
- Sustainably sourced from independent, cruelty-free wool farms.
- Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.
The material is the best Merino wool I have owned to date. Couldn’t be happier.
Replacing my entire wardrobe. I can only say the hype is real.
Can wear a dozen times without washing. Just hang on a hook to let sweat dry and it’s as good as new. This thing is magic.
Perfect for Travel
YOU’LL PACK LIGHTER
With clothing that doesn’t smell after every use, you can pack less, allowing you to ditch the suitcase and travel with just a small backpack.
YOU’LL SAVE MONEY
These days, most airlines are going to charge you for anything other than a carry-on. Start packing lighter and doing less laundry, and save your money for the real experiences.
YOU’LL SAVE TIME
Never check luggage or worry about airports losing your stuff. With fewer but better clothes you’ll blaze through airports like a seasoned pro.

I’ve been on a quest to find a merino bra that’s supportive and fits well—I’ve finally found it! It’s perfect for adventurous travel because the merino wool prevents odor from taking hold, even when hiking in warmer weather.
- SNSharon N.Verified BuyerReviewingWomen’s Merino Bra Sand / SI recommend this productRated 5 out of 5 stars8/28/25PERFECT for Hot and Humid Weather
This merino wool bra is a game changer. We just got back from three weeks in Japan. It was scorching hot and humid, but combined with this bra and the dress and t-shirts, wow! Will never look back.
- JBJune B.Verified BuyerReviewingWomen’s Merino Bra Black / MI recommend this productRated 5 out of 5 stars8/28/25Looks good and comfy
I’ve been looking for a merino wool bra that I can wear to workout and for everyday outfits. This one does both.

I have been looking for a low-tox alternative bra and this one is great! It is comfortable, supportive, and the material is soft.
- SJSusan J.Verified BuyerReviewingWomen’s Merino Bra Sand / XLI recommend this productRated 5 out of 5 stars8/26/25Best merino bra for ample bosom
I am 5'2" and wear a 34 E. When I contacted Unbound about the best size to order, they told me that their bras were designed for up to a D cup. I'm delighted to say that the XL is a perfect fit. I've purchased merino bras from several other purveyors (Icebreaker Queens Cup, Wool&'s Roam , Branwyn's Busty) and can honestly say that this is the best in terms of shape and comfort (no uniboob and doesn't show under a tee or merino dress). The only thing I'm not fond of is the high percentage of synthetics (40% -- yikes!) I'll have to see how it performs in heat and with exercise). I tried to order another (two) -- but, they are out of stock. Thank you! Bring it back soon (along with underpants with more coverage)!
