Crafted with a forgiving and breathable merino wool blended fabric, this lightweight bra is ideal for everyday use and ultimately offers paramount comfort with its no-side-seam construction while the adjustable straps make fine-tuning your fit a breeze.

    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.

    Hi Ingrid,
    Thanks so much for taking the time to review your Icebreaker Siren Bra. We are so pleased you're a merino lover and that this bra is doing all it was designed to do! Our favorite feature is the no-stink aspect as well. Please reach out to the Gearhead team if you ever have any Icebreaker questions, they are all experts.
    Have a great day and thanks again,

    Not a great fit

    • Familiarity: I returned this product before using it
    • Fit: Runs large
    • Size Bought: Medium

    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. :/

    Hey Cynthia,
    Sorry to hear that this bra wasn't just right for you. Not sure if you're still in the market for a great bra, but the Sprite Racebrack or the Tiki bra are both great options. Happy to answer any questions regarding fit!

    Form and Function.

    • Familiarity: I've put it through the wringer

    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 Love It

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    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.

    Nice bra-- good to find one that's wool

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small

    I originally ordered this bra in a size Small, as I'm right on the edge of small and medium (I'm a 34B, with a 35- 36 inch bust). It was too small-- the band was very tight and I felt like I was spilling out of the cups a bit. Returned it for a medium, which fits MUCH better-- but I really don't like the very wide, tight chest band. I will be removing it and replacing it with a 1/4" wide elastic, and then the bra will be perfect for me.



    I do really like that this bra is a pullover-- no uncomfortable, narrow, poky hook-and-eye thing in the back-- and that its design leaves the center of your chest entirely exposed-- it's much cooler than a sports bra because of that.

    hot as balls...

    • Familiarity: I've used it several times

    I bought this for sleeping in my insanely hot apartment. It's wonderful. It's comfortable enough for sleeping and stays very cool throughout the night. My only qualm is with the cup size. I'm a 38 C and the XL fits my back and shoulders very well but, I get a little double boob. Be warned.
