The 125 Racerback Bra is highly praised for its excellent fit, comfortable feel, and supportive nature, making it a great choice for those with larger busts.

"Very happy with purchase and fast delivery. I received within a week of ordering from New Zealand to Townsville. (quicker than local post) I'm a 12 B/C and brought size medium. I was worried reading some reviews about the fit but it fits me perfectly and is super comfortable. Its definitely a low impact bra but just what I need for hiking EBT. Reviews also complained about the label, but this was super easy to unpick to remove. Thanks Icebreaker!"

"I already had it in orange and was waiting for it to be available in black. Great support for hiking, I wouldn’t wear it for running. Breaths, dries fast and super comfortable. 5’2’’ 145lbs 36-C bra size L purchased size large and fits perfect"

"A welcome replacement for my polyester workout bra."

"Best wool bra for women on the market."
— Lise S. (5/5)
"I've been working to make a natural fiber closet, and quality workout gear has been the hardest to find. I tried a few brands, and this bra is, by far, my favorite. Comfortable. Covered. Supported. It's everything I wanted. I found the size chart to be accurate (the chart put me in a large even though I usually wear mediums in icebreaker tops). Highly recommended."

"I got the pink one in both small and medium. I'm 5'7, 132 lbs, 28" underbust, 36" bust (32D or 30DD generally fits best), and both sizes were too small in the bust. I tried the medium first and didn't even bother with the small because medium was like wearing a medical-grade compression garment (except for the band, which was a little too big, maybe because the bust was pushing the band out). I was spilling out of the top and sides. The band on the small is about 3 cm smaller than on the medium (I measured - small is 29 cm across, and medium is 32. 5 cm). I could try a large, but I'd have to take it in or safety pin the sides to make the band tight enough, and I'm not sure it would be long enough in the body anyway, as the medium was a little short and the band was pulling up at the back a bit. Both small and medium are the same length, so large may not be any longer in length. Total bummer, as I like the colour and the fabric and the overall look. Why can't sports bras have sizes that work on people who aren't rectangles?"

"I just bought this bra in size Small and now I wish I had bought two!! I am 5"3, 120lbs and a 32C with a muscular build. This is a perfect fit if you wear a size 32 bra which are hard to find. The support is good too. Some of the other wool bras don't have enough support for someone who is closer to a C cup and wearing them for athletic activity. I know I am going to get tons of mileage out of this bra and will definitely be buying another one in the future. Please don't change the design and fit. . . you nailed it Icebreaker!!"

"It was a bit stiff and on the tighter side at first, but more comfortable after the first couple wears. I use it for backpacking and hiking mostly. So far it seems more durable than other merino bras I’ve had. I don’t use the removable cup inserts much, but good to have them for more contouring. I am a full 36C size in a regular bra. I got a Medium. Sometimes it’s a fine line between support and comfort!"

"Very confortable bra for doing sport, I use it for cross country skiing and running and it don't impaired breathing."

Find the size that fits you best based on people just like you.

Use the chart below to determine your size. If you’re between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different sizes, order the size indicated by your chest measurement for tops and your hip measurement for pants.
