Icebreaker Siren Bra - Women's for Sale, Reviews, Deals and Guides

This bra feels more luxurious than any 'lingerie' company bra. The fit is nice and snug and support is great for every day or even a run if you have a smaller cup-size. The off-white color is feminine and very flattering. Surprisingly sexy! It does get occasionally itchy being wool, but I can get several wears before needing to wash. Definitely hang dry to keep it from pilling or shrinking. I do wish it were more seamless under clothes. There is a pocket at the top of the cups, visible over clothes, that imply you might be able to add removeable cups to it, but the triangle shape would definitely not fit standard round insertable cups. I'm wondering if Icebreaker makes cups to add that would smooth out the fabric and make it more no-show. Overall a lovely and functional bra.

The elastic band is thick and feels tight. The cups are small. I'm not overly endowed and, according to the size chart a medium should be my size, but I'm spilling out of the cups and it is not a flattering look under a fitted t-shirt. I'd definitely order a size up if I had it to do over again. Maybe I'd like it better. I guess the other option would be to lose 10 or 15 pounds.

Love this bra so much. They are not kidding when they market it as wool with sex appeal, yowza! Super flattering fit, does NOT look like a sports bra. Sounds vain, but it makes you look really hot. It's incredibly comfortable you barely notice you're wearing anything. I normally hate getting into sports bras but the Siren has just enough stretch that it isn't uncomfortable to pull on. It didn't absorb any odors. I tossed it in the laundry machine and it didn't fall apart or pill. I'm a B cup and the small was plenty supportive for casual/low impact activity. Looks great with the Siren Sweetheart top. Icebreaker is dangerous for my wallet...

I'm a bike commuter, and I've started converting as much of my wardrobe to wool as possible for its sweat wicking, non-smelly, and temperature regulating properties. I was very skeptical of this bra when I ordered it, but I'm so glad I took a chance on it! I'm pretty small chested, so I don't have to worry about as much support as some women, but I definitely want some support when I'm hitting bumps and going over railroad tracks at 20mph on my ebike. This bra delivers! It's so comfortable I forget I'm wearing it. It's so soft and never itchy. I did end up purchasing swimsuit or "modesty" inserts from Amazon for the pockets in the cups... I'm wearing this bra under my clothes at work, so I needed some coverage there. I ended up getting a second bra and I wish I had more so I could live in them permanently.

So cute and comfortable! I was looking for a moisture wicking, odor resistant merino wool sports bra that didn't cause uniboob and this is the one. I highly recommend this bra! It's great for working out, and casually.

I just put this bra on and I'm already psyched on it! I am a 36A-B and I ordered the Medium since I always feel like things are tight around my rib cage. I ordered this bra because I'll be doing a lot of backpacking this summer and I just wanted a quality item that isn't just a polyester sports bra that smushes instead of supports! Granted, it is a casual fit, and I could understand if you need more support that this may not be a great bra for high activity days, but for me it's perfect. I relate to some of the other reviews, as I have always hated wearing bras - mostly because they just never fit right and sports bras have never been super flattering, supportive, or comfortable for me. This has been the best thing I've put on my body in a long time. The Dusk color is also beautiful, so it makes me feel GOOD to be wearing something that looks nice and isn't just a classic black sports bra. Thanks Ice Breaker for an AWESOME product!

This bra does not provide enough support for even walking. I wore it on a backpacking trip and it's good I was just with my fiancee, because the sisters were jiggling with every single step. And it's not like they're huge either --I am a 34 C (got a Medium), which is about as close as you can get to the middle of the road. So this bra is basically only good for lounging, but it's less comfortable on the skin than my $10 Hanes lounge bra. So what's the point?

I have to start out by saying that I love all things Icebreaker and this is no exception. Comfy and functional but more fitted and flattering than a sports bra. It has places for pad inserts which hold tight. Great for traveling as easy to use hiking etc as well as out in the evening and easy to hand wash and hang dry.

I just got this and can tell its going to be my new favorite casual bra. Its supportive and comfortable enough to last through the day and on light walks. I love how it fits, the material, and the cut. It will work under a large variety of necklines and shirt cuts. I love it!

I refuse to wear regular bras, always opting for the most comfortable options but typically struggling to find the perfect bra to fit the bill. This one does just that. Its the perfect blend of comfort and practicality while maintaining a feminine look that works well under many different types of tops. It has become something I wear daily. I will definitely be purchasing more of these.

I have always hated bras. As a small chested person I opt for the most anti-bra bras I can find, so I have been wearing sports bras or bralettes and going braless for years. This bra has no wires, padding, or clasps, and yet it still offers support and a really flattering shape. I have been smashing my boobs against my chest with ugly bralettes for so long that I forgot what they are supposed to look like. I love the cut and feel of this bra and the wool makes it so I almost never have to wash it. I will say if you find it itchy at first, give it a few days. My skin got used to it around day 3 of wear, and now it is absolutely my favorite bra. Thank you Icebreaker and please never stop making this!

This bra was one of my favorite purchases. It is comfy, soft and keeps me feeling supported. Icebreaker thought of more than just function with this piece. It also has a flare of fashion. The cut is very flattering and can be worn under a vneck style shirt.

I am a firm believer in all things wool. This bralette is no exception. I am 34c and got size M which is just so comfy. If i had larger boobs i dont think this would support very well, but for my boobs i can wear this hiking, around town, in dresses etc. I wouldnt go bouncing on a trampoline and expect super support but i love it for less active activities. climbing, walking, hiking, biking, loafing, working, ooooo, its just so comfy. No itchy tags or cumbersome clasps. Like wool, after excessive use it doesnt stink.

The fabric on this bra is great! It is very comfortable and stays in place. I feel that I usually have to adjust or move around my straps but have had no problems with this

I love the material but the cups just are not flattering

This is very comfortable for a casual bra. I only dropped it down a star because I think that it gets a bit hot in summer months.

I have a couple of the Siren sports bras and love them, so I gave this one a shot. Bought the same size (M--I'm a 36C) and while this fit fine in the band, the cups were no bueno. There was extra fabric puckered up at the top by the straps, like the cups were too big. Did not like. :/

Simple design, easily adjustable and I love the wool blend fabric. Way comfortable.

This was purchased for a multi-month backpacking trip on foot in hostels and camping. It was my favorite one. The fit is nice as it still gives you some form as opposed to a shelf bra. I ordered a small that fit well and I'm a 36A/34B. I washed it when I could but never had a problem with it. It was comfortable even with my pack on for hours. I was comfortable during fly fishing and chopping wood too, no restrictions. I never felt it was too thin to nip out through cloths either. I bought it in black.

I had two of these bras for a two month backpacking trip and they worked wonderfully. They don't get as stinky as regular bras, because of the wool, and they fit really well. They are also so comfortable you forget you're wearing them. Being a huge fan of comfort means that was very important to me.
