This bra is amazing! For reference I typically were a 40DDD. I purchased the XL after reading some of the reviews and couldn't be happier. It is so soft and there is no bulging anywhere. I will likely be purchasing another one to add to my collection so I'll have one to wash and one to wear. My only request would be to please begin making these in skin tones like brown and beige.

Fit was amazing! Bigger chest friendly

Normally I wear a 40DDD (or 40F). I was skeptical but read the reviews and thought it was worth a try. I am so thrilled! I tried it on as soon as it arrived and never did I expect the fit to be as good as it is. There is nothing binding, there are no wires and the support is great. For reference I am 59 years old and finding a bra that fits like this has been unheard of up until now. There is no "back fat" or budging out anywhere. To Flowool I want to say a big thank you and please consider making these in other colors specifically skin tones like beige and brown. I don't know that I would wear anything else if I had one that is skin tone that I could wear under anything. The bra is just that great!

Best Bra ever. I have tried EVERY wool bra on the market. Great for 34D's that need extra support due to time and gravity. ;-) Great for highly active activities and keeping your innermost layer dry when you stop for lunch skiing, cycling, hiking or if you go straight from activity to streetwear. Please, for the love of God, come out with a white, off white or light colored skin tone version this bra. PLEEEEESE. Many of us wear light colored sun shirts, cycling jersies, hiking shirts or tank top / singlets where we do not want black to show through. If you had a light version this would be the only bra I own for active life AND day-to-day. I have bought 3 in black. I have tried your other triangle bra which comes in light colors. However, it does not work for large chests or active endeavors. Returning those and waiting anxiously for you to come out with a light colored version of this exact bra with padding sewn in. So confortable and the BEST.

The sports bra was easy to get on and very comfortable. The cups for me being a larger lady could by bigger for more coverage. However under a t shirt it is not always showing. The bra held my ladies in perfectly. Could you come up with a bra that allows a regular bra straps or ones that can cross too? Thank you.

Hot yoga instructor here…Ive been on a search to find less harmful, more natural activwear and gave this sports bra a try. 3 stars for the well-fitting structure! It is a well-fitting, basic sports bra with slightly less toxic wool-blended fabric against the skin. Cons: it had a bad chemical smell coming out of the package and there is an irritating corner seam in the back that scratches my skin. I will be returning as i cant justify spending $90 on a sports bra with these flaws.

Comfy and very well made. Love that the padding is sewn in permanently. Only dislike is the scratchy bit on the closure. I had to clip the sharp corners and still i can feel them when the bra back strap is clipped closed. But otherwise it is nice and supportive.

Loving this sports bra! It’s supportive, I like the internal padding and back hook. I haven’t run in it yet but I think it will hold up well!

I appreciate that the bra has pads. I thought The pads might be removable but they aren’t. Instead seem to float inside the bra but also not move around—hard to describe. The bra is super soft, air dried overnight which was important for me as I’m taking it on the Camino where I may need that feature. I hiked9 miles in the bra and no chafing whatsoever.

Hello there. I'm writing you to say that you have made basically the best bra in the world! I have tried every sports bra known to man and at every price point that exists. While I have a 34D chest I used to be a 34 DD before having 2 kids and going through menapause. I still need padding for modesty and shape. The problem is all of the great hoisting bras with modesty padding get wet, soggy and smelly. They also can't stay on a your body post workout or the back end of all day activities. They don't dry quickly and bacteria build up on your skin is a real thing if you don't change your inner layer which is always the weak spot! I have also tried every Smart Wool bra on the market, at every pricepoint. I've tested them from daily gym workouts to Trail runs, backpacking and long cycling events. They all make you a unaboob and most are lacking the support required for larger chested women that are fighting the effects of gravity with age!. Any that have padding are removable padding which moves around and looks terrible and is a pain to upkeep and reposition after washing. You have made the magic bra the best one ever! Great shape, great support and modesty padding built in that does not sog up! You cracked the code. No stink after workouts possible for travel or multiple back to back day workouts or just going on a long bike ride where you stop for lunch and start again and aren't soggy freezing and feeling like you need a new underlayer! I'm so happy with this bra I literally don't have words. I'm telling everyone I know. All the dirt girls, all the dawn patrol girls and all the spa girls too! So first of all this is a giant thank you! Secondly it is a big request for a second act... Please please PLEASE come out with a version in white. Also if you could come out with the version that is not T back. This would be the only bra I wear! It works for everyday wear outside of fitness. Looks great feels great everything about it! You need a light color version to be worn under light clothes both for workout and everyday wear where the black shows through. I would buy multiples and I know my friends would too. Please white.

Best sports bra ever!!!!! Had a weird ordering experience but all worked out. Customer service was honest and helpful. Please make this in lighter color. Please!

This is absolutely the best sports bra out there!. I am 57 years old 34D. The "girls" need serious hoisting and separating while being held in from bounce. I have purchased every brand of SmartWool bra on the market and none of them fit the bill. This had left me with padded regular sports bras that get wet, smell, are slow to dry and also have bacteria filled up. They also require washing every time. This is a problem on long bike rides where you get sweaty and stop for. Then get going again or for after the gym when you might be running errands and doing other things without time to change and shower immediately. All the great gear in the world doesn't do you any good if weak link is your underlayer! This is the first Smart Wheel bra I have found with sewn in padding for modesty and a little extra shape which is fantastic! The Smart wall fit is perfect and extremely comfortable. And I can't believe it but it gives me the support I need for all but crazy jumping jacks or trampolines. This is my go-to under bike jerseys, for trail running, for the gym and I can't wait to use it for skiing as well. Yes yes. I never write reviews but this is such a great solution. Begging you to come out with a white or skin color to wear under lighter colored tops. If that becomes available this will be the only bra I wear! Thank you thank you for designing a smartwell bra with padding that also dries quickly and doesn't stink and gives enough support without making you look like a mono boob! So grateful and happy.

The perfect wool bra. My very favorite.It'sadjudt able, comfortable, pads are great thickness and sewn in place. It dries hung overnight.

It’s a great idea, and I know this product line is going somewhere. However, the attachment part of the back of the bra is uncomfortable for me. I’m not sure if there are loose threads but something is scratching me. I wish you just had a simple overhead bra like this.

Appreciate you sharing this
Sorry to hear about the discomfort at the back, that’s definitely not the experience we want. It could be related to the stitching or hardware, and we’ll share this with our product team to take a closer look. You’re also welcome to reach out to our support email and we’ll help you sort this out.

Love this bra! The material was weirdly itchy the first day I wore it, but softened up somehow after that. I wear this for gym and jogging workouts, and its perfect. The stitched in padding isn't excessive and I feel secured and modest. Please make more colors!

Chest pads! The manufacturer really gets it—I absolutely need these stitched-in pads for my bench press workouts. Love these fixed-cup pads the most! Hope more colors become available in the future!

I like these a lot. They give firm support but are also comfortable. The material has a good amount of stretch to make the fit well and also give good support. I am somewhere between an m and a l but I ordered the l and it fit me perfectly!

Great Sports Bra

This is my 2nd order of this sports bra and I have to say, it’s probably my favorite so far. The bras are nice looking, made very well, and are a nice firm fit - which I love.

Surprisingly nice

Honestly really good. They're probably a medium-high level of support and super comfortable. I'm a D and was able to fit comfortably and still feel nice and supported.

Comfortable and True to Size

I go to the gym just about every morning so having a supply of sports bras makes it so I have to do laundry less frequently. I run and lift weights in these, and they hold up fine. For reference, I am a 34D and I have no issue with bounce or control. If I were doing super high impact, I would probably want something with more control, but for my purposes these are fine.

These sports bras are super cute, VERY comfy, stay in place, and are a great value for the money. I could never find a sports bra that fit me right. These fit perfect. True to size.
