Really happy with the purchase

Purchased my first Icebreaker bra looking for activewear for running. I am 32C and usually wear M but going for S was a great idea for high intensity activities like running. It's super comfortable to wear and you don't feel like you're choking like you do in Polyester. Definitely gonna buy more!!

Shoulder straps stretches out

Love the merino wool thickness, and the straps fit perfect when I tried it on. I decided to keep it, but the strap length stretched out, so bad that I'm constantly pulling up the straps, or adjusting my breasts so they almost don't fall out. I bought a medium and so disappointed. I'm not that big, I'm a 36 C.

The Ultimate Sports Bra

[This review was collected as part of a promotion.] Extremely soft, supportive, breathable, and comfortable. No "nipping out" even when the pads aren't in it. I loved it so much that I promptly ordered a second one. I've worn them walking, cycling, running, hiking, weight lifting, and XC skiing. A winner in every occasion so far. If I had to pick only one sports bra to use from now on, it would be this one. The different fabric weave types are optimally placed for breathability and comfort. Also, with the wool content, these bras stay odor-free and can be worn multiple times before washing. And the lyocell makes them very quick-drying. And I used them across the range of low- to high-intensity activities. The band makes it a perfect style for clipping on Garmin's women-specific heart rate strap too; that HR strap requires an actual band, as opposed to seamless design. Please keep making these forever and in lots of colors.

Love this Bra

[This review was collected as part of a promotion.] This is my third time buying this bra--it's the most supportive one I've found in natural fibers. I wear a Medium and am a 32DDD--I love that it's lightweight yet still pretty supportive. Would love to see one come out in a beige or ivory color!

Favorite hiking bra

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

Quality piece, elastic too tight

I wish I could have kept it, but the elastic was too tight. I’m afraid the next size up will be too large. Feels amazing though, and well made.
