My New Everyday Bra

[This review was collected as part of a promotion.] I love this bra! So comfy. Note that it runs small. I normally wear a M but ended up needing a L. My bra size is 34C but I'd rather it be a tiny bit large than too tight (I tried both sizes).

Everyday Use

[This review was collected as part of a promotion.] This has become my daily wear bra; I initially bought one to use for hiking, but liked it so well that I bought several to wear everyday.

Comfy But Runs Small

[This review was collected as part of a promotion.] Bought 3. I have eczema so during flare ups they can be a bit itchy, otherwise I find them soft and comfy. Would recommend sizing up if you're on the fence.

Nice Bra

The fabric is nice for hiking and it has removable pads. I like the color and texture but I wish the straps were thicker and more like a sports bra. I wear this a lot and I will probably get it in another color.

Best Outdoor Activity Bra!

This bra is highly recommended! I have been wearing it for hiking, skiing, backpacking, and long-distance travel and it performed well. It stayed fresh, even after six days of backpacking in New Mexico and 10 days of TMB . It's incredibly comfortable, supportive, and breathable.

Perfect!

[This review was collected as part of a promotion.] This is my go-to bra for everyday, camping and travel. It wears well, is very versatile and extremely comfy. I've used this bra for at least 10 years and own several.

My Go-to Travel And Daily Bra

The Siren Bra has been great for everyday wear and light support. It’s comfortable under a T-shirt and holds its shape well without digging in. The merino makes a big difference—I can wear it for multiple days and it doesn’t get stinky. It’s not designed for high-impact activity, but for daily use or travel it’s been a solid choice.

Great Bra

[This review was collected as part of a promotion.] The merino wool fabric is very comfortable and wicks away sweat. Love my icebreaker clothes! I sized up to a large since the first icebreaker bra I owned was a medium and was a bit too snug. I typically wear 36b.

Flattering For A Small Bust

[This review was collected as part of a promotion.] This bra has a flattering fit and is such a pretty color. It pulls on, which is convenient, and looks nice under a t-shirt. The wool is a bit itchy, but I hope it softens with time.

Best Bra Ever

[This review was collected as part of a promotion.] I love this bra. I I initially held off from buying it because I thought the center seams would look funny under shirts, but I was wrong. This is the most comfortable bra I own. I love that it has a thin removable insert/pad for modesty. I actually bought the pink one as a second one after the first one I bought fit so well and felt so great.

Super Comfortable!

[This review was collected as part of a promotion.] Buying a matching set of Merino undies feels surprisingly sexy (and of course, comfortable). I took out the padded liner. Comfortable, pretty smooth under clothing, great for hot sticky New York summers.

This bra is very comfortable. I've worn it on multi day backpacking trips and it stays comfortable. I hung it up overnight and it never smelled bad.

Love It

[This review was collected as part of a promotion.] No complaints. I always wait for this one to be on sale. Absolutely love it.

Love These

Bought my first one of these merino wool bras at REI years ago for a road trip and instantly fell in love. I’ve since gained a little weight and had to size up—and they’re still amazing. I just bought two more, and honestly, I never want to wear another bra again. These are incredibly breathable, flattering, and supportive—but the real game-changer is how well they handle heat and humidity. Even on muggy summer days or after a long bike ride, I’m not left with underboob sweat or dampness. The moisture-wicking and odor resistance are top-tier. I’ve worn one out riding, and the next day it’s dry, fresh, and totally wearable again. No clamminess, no smell, no stiff seams or heavy fabric. This is hands down my go-to everyday bra—not for workouts, but for everything else. I seriously need to stock up because nothing else compares.

This Bra Has Saved My Summers

[This review was collected as part of a promotion.] I know a lot about wool, so I expected good results from a merino bra but y'all: I did not realize how effective this would be at wicking away boob sweat. I live in a hot and HUMID climate and in the depths of midsummer it feels like someone has set up a sauna between my breasts. I was a little worried about the wool retaining heat but if it does I haven't noticed and if it doesn't, the humidity control more than makes up for it. This is now the only summer bra for me; I pledge my fealty to it and no other.
