Icebreaker

Siren Bra - Women's

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.

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.

Excessive Irritating Multi-Language Tag

I can’t speak to this product’s comfort and wicking ability because it came with giant, irritating, excessively large tags in multiple languages sewn in to the seam of the garment. When I tried to remove the tag carefully I ended up needing to mend the garment before I could wear it. What kind of company would sew giant, excessive, irritatingly large tags into womens undergarments? Clearly these tags defeats the purpose of buying clothing made from natural fibers.

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.

Work in a restaurant and it's great for wicking sweat

[This review was collected as part of a promotion.] I bought this bra because I needed a bra to keep me dry while working. The icebreaker bra is great at wicking moisture and staying dry when I am sweaty. It does the trick and I love the cup shape.

Comfy and keeps smells down!

High quality and very cute fit. Comfortable. Highly recommended! Keeps smells away for long hikes.

VERY comfortable, and it looks like it too

[This review was collected as part of a promotion.] 5'5", 135-140lbs, 34C - This is SO comfortable and it looks like it. Not much support, bulging at lines, too embarrassed to wear this in public. This is for A/B cup gals not C+
