Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 2 out of 5 by from Elastic band prematurely wears Owned since Fall 2021. I wear this bra more in summer as it is so lightweight as a daily bra or for light activities and gardening. I machine wash in tap cold water (i don't use warm which is recommended) and hang dry. I pulled it out to wear today and was disappointed that the elastic bottom ks stretching and puckered, which I would expect after more years of wear and heat exposure. This hasn't happened with my other Icebreaker sports bras which I wash the same way.

Rated 4 out of 5 by from fit small (This review was collected as part of a promotion.) nice material, comfortable but fit small. My normal size is S and I bought it in size M and still, it feels very tight.
Date published: 2023-03-16
Rated 4 out of 5 by from UPDATE - I feel like they Cheaped Out So I decided the S band was way too tight and when compared to my current S Siren bra it was indeed around 2 inches less of band material. (not sure how much stretch occurs but I have not worn my older S that much). SO I took it back to the store to exchange for the M. To my surprise the M in store had the padding in the cups! Not sure why there's inconsistency here with the padding as it was the same colour / style, straight size exchange. I do think though, that they have made the band tighter / smaller than in previous years so you may wish to size up.

Rated 3 out of 5 by from I Feel Like They Cheaped Out :( Been buying this bra for years as it is comfortable. The band is a little tighter than I would like but sizing up makes the cups too loose. My issue is that the bra no longer comes with the removable padding. This was the only way the bra provided any shaping, without the pads there is zero support and no coverage in a T-shirt if you know what I mean. Not nearly as flattering as with them. You can add your own but at this price point I find it irritating.
Date published: 2023-03-05
Rated 4 out of 5 by from Perfect for Compact/Active Travel I substitute these bras for traditional bras while traveling due to how small they pack, how clean they feel, and being able to wear for a few days without smell/sweat concerns (active/outside business travel with small carry-ons). I wear a 36C and went for size large. It's very comfortable to wear for long periods of time and provides support without the compression of a sports bra. The only reason I didn't give this bra 5* is because of the straps - I wish they were wider as they do cut into my skin a bit.
Date published: 2023-03-02
Rated 5 out of 5 by from Comfy and low maintenance. (This review was collected as part of a promotion.) I would say it offers more support than expected, especially with the padded cups. I will wear this under all of my dark clothes.
Date published: 2023-02-21
Rated 5 out of 5 by from No more slightly sweaty armpits This bra looks amazing and feels amazing. It's perfect for work, hiking, and literally anything else. I don't use it as a workout bra but I would use it for climbing. Plus the material makes it so I dont constantly have slightly damp arm pits. The material is sometimes a tiny but itchy.
Date published: 2023-02-21
Rated 3 out of 5 by from Merino bra I wear 36B and found the Medium too tight around my chest. Also I wish the straps were a bit wider to not cut into the shoulders.
