Smartwool  Intraknit Racerback Bra

There's is a lot to like about this bra. The fabric is soft and comfortable. I bought it in the pink sugar color so I could wear it under my white shirts and still have good support. It works well for that. It is cut low under the arms so it doesn't rub. I purchased my first one according to the sizing chart. I am 5' 4", 116 lbs and a 36 A so I bought a medium. It was way too small. So then I bought a large. It is much better, but still very tight. It will be good for hiking, those who run and anyone who needs a lot of support. It's still a bit too small for less rigorous activities. Not something you'd want to wear all day long. So size up!!

I bought this to hike the Camino during the summer of 2026 during a record breaking heatwave. I am a 36 DD so I bought an XL and ditched the pads. It is a double layer so there is plenty of coverage. It was extremely comfortable even after getting sweat soaked. It would dry overnight and I rinsed it out every three days or so. I had a second backup bra I put on after the day’s hike and a shower. I am someone who gets rashes really easily but this kept my skin clear and comfortable. Definitely recommend!

I wanted to love this bra, but actually can't even stand to wear it for more than a few hours. The band hits at a weird spot, like 3 inches below where a bra band should be, so there's a weird gap underneath the boobs. It is not supportive AT ALL, like it is actively smashing my breasts downward. . . which sounds like it is too tight, but is not too tight at all. The racerback behind my neck keeps creeping up, while the front slides lower and lower. I could see this maybe being ok for someone who has small breasts and wants more of a cami feel, than actual support, but if you need any kind of support I would avoid. I am a 36C, 150lbs and 5'8"". Typically wear a large (which I bought).

Almost everything is perfect with this bra, but a big con is the smell of chemicals (maybe dyes?) that it has. It is nauseating. I recommend that you wash before wearing with borax and laundry booster to get rid of the odor. Still, it won't go away. I got it on sale, and I washed it, I'm not sure I can even return it. Worst thing? I got two: one in this style and the other in a similar style. Both have the same problem. :( Good thing: it's true to size (at 5'4' 118 lb), and it looks durable. Also, it is perfect for yoga, everyday activities, and hiking. It keeps everything in place. LOL.

For the first while it's a great sports bra, comfy and supportive and can be worn a lot without smelling or needing to be washed. But. It stretches out a LOT and becomes completely unsupportive. I've gone through at least 5 of them, and for how expensive they are, they really should last longer than they do. It's not getting holes or anything but it completely loses its support. I included a picture of 2 of the same bra, same size, bought about a year or so apart and you can see how much it has stretched. I'd want this issue fixed, or lower prices if I have to replace it every year

My days generally pass through many places and variable activities. It may be cold when I walk to work in the mornings, followed by sitting in a hot office for many hours, and then a quick workout before some grocery shopping on the way home. This very smart piece of wool does it all: takes zero time to figure out what to wear in the morning, regulates to a comfortable temperature all day, and, as a bonus, only needs washing when I feel like doing it! Well worth the investment, especially when the company gives a discount or puts things on sale at the end of the season.

This bra is amazing. It’s super comfortable and breathable. Must have for hiking. It runs small, I would normally be a large and an XL fits perfect. For reference I am 5’9, broad shoulders, and I’m a curvy 36 C. Didn’t even blink at the price, once I tried it on I HAD to have it. I prefer it over my lulu sports bra.

I purchased this bra for a backpacking trip I have coming up. My main concern was sweat and smell and secondary was that I could use this as a bathing suit in the lakes should I want to take a swim. I love it, I used it on a recent shake down backpack and it feels great. The sweat dries quickly. The pads are removable and I like them for 'privacy' but I might remove them on my multi day trips especially when it's hot. Fit is great, I purchased a small and my normal bra size is 32C or 32D.

I have started to upgrade all my athletic wardrobe to wool. I was hoping this bra would be a staple for that but it is so many layers of fabric that if I go for a run and sweat, it holds so much sweat right on my body that I get really deep chills and need to go take a hot hot shower. It's ironic that the description says something about how you know about bras that you want to take off right away. This is that bra for me! I can't even plan to wear it if I know I have to run an errand after I go running. why did they make it so thick!?! This is one of my main criteria for a good running bra so I was bummed it is constructed like that. I'm better off with my target bra for a fraction of the price. Also if you think you're gonna look cute with your shirt off you would be wrong. All the smartwool bras are just here too smash your chest down.

I used to LOVE the smart wool bras and I hiked the Appalachian Trail in one. It was so comfortable. I got this new design to replace that bra and it's band is so tight. Here's the kicker… I thought maybe I should use this as motivation to work out so it fits better. I LOST 15 POUNDS and this bra STILL hurts!! i only wear it for the hour at the gym and that's about all I can handle. Definitely would not wear on a big hike again.
