Our tester took this bra on an 11-day road trip and had to force herself not to wear it every day. The merino fabric holds it's shape and keeps cool.
They're really comfortable and I like the material. Plus the brand is sustainable, made for performance, and they're committed to empowering women.
Running, camping, rock climbing, skateboarding, and biking. . . I never want to turn down an impromptu pickup soccer game just because I’m wearing the wrong bra.
With a next-to-skin fit and next-to-skin color palette, Branwyn is changing the game when it comes to chic merino panties (these ain’t your grannie’s wool underwear).
This merino bralette wicked away sweat on an 80-degree hike near Sedona, Arizona, and double-layered fabric across the chest kept us from nipping out on a 50-degree trail run in Kansas.
I can confidently say BRANWYN underwear is the perfect all-day pair fit for the adventurous Colorado yogi.
UNDERWEAR THAT’S BUILT DIFFERENT
Merino wool empowers you to stay cool, comfy, and dry, all day, every day.
This magical material can hold up to 30% of its weight in moisture without feeling wet, so you keep comfortable regardless of how sweaty things get.
Natural thermoregulation means you stay cool when it’s hot and warm when it’s cool — aka always comfortable.
Whether you’re balancing in warrior pose, going full send on a new climbing route, running a 10K, backpacking through Joshua Tree, or walking the dog, our Innerwear is built to move with you.
Seamless knitting technology means no digging, while women-centric construction stays put without riding up, slipping down, or giving you a wedgie.
Our customers say they forget they’re even wearing it.
Merino is a 100% natural, biodegradable, and renewable fiber.
Sheep produce new fleece over and over, and their wool decomposes naturally in soil.
Compare that with polyester, which takes 500-plus years to decompose.
Plus, we use only ZQ-certified wool, which guarantees ethical treatment of our beloved sheep.
LOVE BRANWYN OR PAY NOTHING
Not sure about wool?
Merino is super soft like cashmere!
It works equally well to keep you cool & dry in the summer as it does to keep you warm & dry in the winter.
We know you'll love it! But just in case you don't, we’ll give you a full refund.
I had a double mastectomy with reconstruction and I have problems with nerve pain around my implants, especially in the colder months. Typically when I exercise and sweat, my chest will get chilled. The temperature regulation of this bra has greater reduced the problem. Best part - I can wear it to sleep, work, or exercise! The odor prevention is also a plus as I can only use non aluminum deodorants (which aren’t as effective). Thank you Branwyn!
I was able to get a busty bra and this bralette. I initially fell in love with the busty bra but I tried the essential one back on and I love it! My issue with it at first was that the bottom band rolled down. The problem was I had it pulled down too low. When I adjusted it a little higher it fit perfectly. Their packaging is also great. I've never purchased anything from a brand that encouraged you to wear their items around before initiating a return. I'll definitely be buying more in every color once they're back in stock. For reference, I purchased the large in both. I'm normally a 36A. Both bras are snug and very supportive for my needs.
most amazing perfect delightful bra i have ever worn? check. do you need to know anything else? nope. they're worth it, that's all.
This is what I’ve been searching for! I backpack and snowshoe, so I need a bra that does not hold sweat. Being large busted, this has been impossible to find. I tried the regular bralette in an XL, but the band was too big and cups too small-it rode up and my breasts pooped out the bottom. But I loved the design, especially the knit band! Elastic bands are so sweaty and uncomfortable. This busty version is awesome, everything I was looking for. I am a 36 or 38 DDD, depending on the brand, and the Large busty bralette fits perfectly. It is minimizing on me (squishes me down a bit) because I have soft breast tissue. But I think if I went up a size the band would be too big. It’s perfect for hiking and winter sports. I wear around the house every day. No sweat! No stink. Please keep making this! It is the only merino bra I’ve found, after 5 years of searching, that actually fits and has a functional and comfortable band.
First I wore for a solid 24 hours and these held up in every way. No moisture, no funk. Cool! The next test was to wear them while working on a farm. I was dripping in sweat and these undies never lost their shape or felt super gross like “regular undies.” They didn’t get nearly as funky either, if you catch my whiff, I mean drift. I hand washed every night with Castile soap and let air dry and they were good as gold the next day. I will be upgrading my underwear drawer after this. Also looks cute as a set with the matching bralette. You would definitely look cute if you took all your clothes off and jumped in a pond to cool off ;)
It’s definitely cooler and less clammy than the usual bra in summer, and extremely comfy. Flattering, too.
But the best is how well it works under my wetsuit for salt water swimming and surfing. Keeps its shape, is warm when wet, and is much less chafe-y than a nylon bikini top. (Why did wool bathing suits go out of fashion?) Fabulous!!
I absolutely love these bralettes. I bought one and loved it so much I bought two more. These are the best for wearing around the house, running errands in, and traveling. Supportive without being restrictive, comfortable without looking sloppy. They have flat lines so they fit great under t-shirts. I get warm and sweat quite easily, so I wanted to find a bralette that could handle that - specifically merino wool. These bras wick my sweat away and don't feel heavy or sticky. I wear them pretty much everyday. Highly recommend.
For reference, I'm 5'2", 120 lbs, 34D, and ordered size Medium.
This is the bra I’ve been looking for. Comfortable, breathable, zero itch. I want to replace all my bras with this one.
These rock! I’ve been only wearing the bralette for over a year now, and the underwear are just as buttery and perfect, why shop anywhere else for inner wear from now on!? I did size from my typical size in store bought underwear.
Love love love these, and slowly phasing out all my other undies. So comfortable, so stretchy - and such easy care! Cold water wash & hang to dry - they’re dry in a jiffy!
I normally can’t wear any merino wool against my skin, but BRANWYN’s bikinis are super soft and don’t itch my skin when I wear them! I can’t believe how amazing these underwear are for wearing all day at work and working out in too! They stay dry and don’t get super stinky, which is awesome when you’ve forgotten to do laundry and don’t have any clean undies to wear and need to snag a pair from the laundry pile.
This bra is perfect for travel, relaxation, excercise it holds up exceptipnally well to any challenge. I am a 34D and bought the large size as recommended. Great material, comfortable and easy to care for! Highly recommend!
I love the hipster. I can go for a brisk walk and not worry about sweat. They are great at temperature regulation. I stay warm, but not too hot. They feel fabulous, good soft feel. I will be ordering more.
Very comfortable. I forget I’m wearing it. Wicks the sweat away and no odor. Flat band and no hooks. Just slip it on and go. Marino wool is the best. Thank you.
I love this bralette!! It really is better than braless! ♡♡
