LOVE!! I would buy this product again!

I am cup size 34B, 120lb, 5'4", and typically like my sports bras not cutting off my ability to expand my lungs (so not super tight AT ALL), and so I ordered size M to be safe. I am honestly obsessed with this bra! I don't find the straps to be too long like other reviews have stated. I also appreciate lower cut things because I have a smaller cup size. That being said, I don't think it's abnormally low cut at all. As seen on the model in the pics, it's slightly busty, but I think it's perfect! It is buttery soft and comfortable, and still feels supportive for athletic endeavors. I don't sleep or hang around the house in bras, and I would honestly sleep and hang out in it all day! The Passion color is lovely, and I will probably order it in another color or two! The most comfortable sports bra I now own :) Very happy customer!!

Fabric is too thick, not flaterring

[This review was collected as part of a promotion.] The fabric is way too thick, making the body feels too hot when exercising. The shape is not flattering at all on a petite body.

Found it...after trying 3 other merino bras

[This review was collected as part of a promotion.] M had the perfect amount of support for my 36C size. The design is so comfortable for my hikes and the pockets for the cups made this buy worth the investment.

Wool based material is great for keeping odor down

Super comfy but fits a little weird

[This review was collected as part of a promotion.] As a few other people have said- the straps are too long, making the neckline scoop a bit too much in my opinion. Also the band on the bottom scrunches up a lot for me. However, it is so so soft and comfortable that I'm keeping it. It also does give decent support (for hiking, day to day wear, probably not for running) still despite the issues.

Straps too long

Im typically small or medium in IB bras, thought the small worked out but with this type of fabric the small straps stretched some and don't feel as supported. I ordered a size XS and the fit is snug but perfect support. Maybe IB can work on shortening the straps? If not maybe adding some size XS to new color options? Other than fit issues, fabric is super comfy, fabric slightly thick

Straps Too Long, Low Cut, Too Stretchy

I returned this bra. The straps are not adjustable and are far too long for the average female IMO (I am 5'3", so on the petite side, but the straps were about 3 inches too long! Partly as a result, the neckline is too low cut (the distance from the bottom front to the cleavage should be greater also). And, the fabric is WAY too stretchy. I had ordered a S (which is my usual IB size, am a 32C), and decided not to try ordering an XS because it would still have the low cut issue (prob even worse). I do wear 100% merino bras much like this every single day, but (competitor) Ibex no longer makes this style so I am still searching for a new source. IB: please modify this 260 weight one!! I love 100% merino and IB is my fave brand.

Perfect

[This review was collected as part of a promotion.] Have historically worn Athleta but starting to get chafing. This bra was perfect!

Saggy boobs

When I first put this on I was blown away by how comfortable it is. But shortly after wearing it, the bra began to sag. After working out, the straps were atrociously saggy and uncomfortable. As others have noted, this bra would be *perfect* if straps were 1-2 inches shorter. As is, the size small waistband fits like a glove but the bra gives me a droopy boobs feel (and look) that is impractical and very annoying (for reference, I'm a 32D). I contacted customer support but was told that my only option is to file a warranty claim. Icebreaker, please shorten the straps on what would otherwise be a legendary bra!

Very loose weave, arrived used

[This review was collected as part of a promotion.] The fabric is too stretchy to function as a sports top for me. Also it arrived in very pre used condition with lots of pilling. I can see why someone else returned it. Inconvenient, perhaps now that TNF bought out Icebreaker quality will go down.
