Icebreaker Women's Siren Merino Wool Bra

A year ago I had a bilateral mastectomy and went from 34DD to using a prosthesis in an A. I purchased 3 mastectomy bras but they are not always comfortable to wear. In searching for alternatives I found this bra - it easily accommodates my prosthesis (I use a foam one with this bra) and is very comfortable. My scar is a visible in the center because of the cut of the bra, but I don’t wear low cut tops anyway. Writing this review in case there are others in similar situation.

Pricey, but worth the money. Thank goodness for the Amazon return policy that allows me to order in several styles and sizes and keep only the ones that fit me best.I'm slowly transitioning my intimates to wool fabrics, and my medium-impact bras, Smartwool PhD Seamless Double Strappy, are the most comfortable ones I own. The neckline of those, however, isn't cut to accommodate office clothing, so I wanted another bra shaped more like a traditional bra. This Icebreaker Siren seems pretty dang perfect: low-impact, but perfectly suitable for a day that's mostly walking and sitting; and comfortable even when worn several days in a row. I hope it holds up to lots of wear.Pros -- The fawn color is a decent substitution for the Caucasian nude bras it will be replacing. I like that the straps can be adjusted. I also like the pockets in the cups where padded inserts can be placed -- I'll probably never insert any, but it's nice to have that option. (The inserts themselves did not come with this bra.)Cons -- Why, oh why, did Icebreaker sew the dang product tags so firmly into the seam here? Usually, it's just light stitchwork that fastens the tag to the cloth, easily removed by a seamripper, but not with this product. It took minutes of careful close work for me to remove all visible parts of this tag without damaging the seam.I'm a 32A and purchased this in XS. I also wear XS in Maidenform and Smartwool sportsbras.

I am a 32 F but these work wonders for me if I maintain my posture. They also let my breasts move as I move which has helped hugely with circulation and really decreased the number of fibrous cysts I have in my breasts. They also never stink! I love them. That's said, I wish they had a little more coverage as I sometimes fall out when hiking or even just dueing everyday life.

one of my favorite bras. Minimal and perfect for a b-cup. Holla!Oh wait. PLEASE: Icebreaker! stop with the excessive packaging. Totally unnecessary to box one panty or bra individually. You could easily put them in their own baggie or better yet nothing at all. I hate excessive packaging and as an outdoor clothing company, you should too.

The design could maybe, just maybe be a little bit more perfect, but all in all, this is a great piece. Especially for travel with the magic anti-stink properties of merino. This was the only bra besides a sports bra from a high end yoga brand, that I took with me on a 3 weeks trip that included a lot of time in Seattle, the Olympic Peninsula, Vegas and the parks of Utah. After 1 day of wear the high end sports bra was smelly and pretty much unwearable, where this one can go for days. Washes up easily in the sink, is comfortable. I wish the o rings were not visible on the front, so if that part of the straps were showing, it would look like a tank layer and not a bra. Overall, I'd buy this again and again. I don't mind not having padding, and prefer no underwire.

Because band and cup sizes aren't independent, I had to get a M to fit the band but then the cups are a little too big (I've been told at fitting stores that I'm a 34 C but can also wear 36 B, ah to be an in-between size). It still fits overall, just a little bit of puckering in the cups, which if wearing a tight shirt you can see. Construction is fine, material is great. Fits well enough that I'll keep it, but I won't order more. To echo previous reviews: what's up with the excessive cardboard packaging?

I bought this for an upcoming trip since I've read such great things about merino wool undergarments. I've only worn it a few times for normal every day use, and it's very comfortable. But, like a lot of other reviewers, I wish that Icebreaker would listen to its customers and make the cups larger on the larger sizes. It's kind of ridiculous how narrow they are - I'm hoping that I don't slip out while I'm hauling luggage...

Odor free wear after wear, great coverage, and washes and dries fast. The cups are a little large for me as I expected but I think the band is just going to be tight no matter what the size. Seems like just a tight fitting design. I got a size medium, I'm 5'7" and 140lbs with a 34B cup. I'll buy one in nude next time I get some extra cash, for sure.

It’s super comfortable and looks nice. I am on the smaller side so for me it was great support for use as a regular bra, as a sports bra it could work but I prefer something tighter for that. As a regular bra I loved it (especially when worn on vacation and it was incredibly hot. It doesn’t smell and washes and dries quickly). It looks good and even though there’s zero padding I didn’t look too flat. Plus there’s an opening to add cups if you want. It’s a great bra.

Always get sore underneath bra when hiking. Although in no way very supportive (no good for running) this bra has prevented me from being very sore. OK if you don’t care what you look like as doesn’t give any shape. I bought large in line with sizing, but cups too small but OK around back. Had I bought extra large it would have been too big in the back. So improvements need to be made.

Perfect. Does not smell of anything even after wearing it for 5 days hiking! Ideal for the Camino de Santiago de Compostela!

Comfy, wicking in hot weather and has enough support not to make a small busted girl look like a boy.

Comfy and easy to wear. Did itch a little the first few wears but it is fine now.
