Why We Like The Siren Bikini Underwear
Quick—ring the alarm! Someone notify the comfort police that the Icebreaker Women's Siren Bikini Underwear is the new sheriff in town. Crafted with an ultralight merino wool combined with a touch of Lycra, these full coverage bikini undies put a practical and comfortable spin on your run-of-the-mill bikini silhouette with their low rise and full coverage. Additionally, merino wool naturally kicks unsavory odors out the door so you won't feel quite as stinky after having run 15 miles through the local trail system.

Look hot, stay cool
It's August in New York City, and between the humidity, heat, and summer thunderstorms, it was feeling swampy outside - and in my pants. I decided to depart from my go-to synthetic seamless VS bikini bottoms and try these. I followed the size chart: I am a 36.5" hip, I went with the Small. (I am a XS in VS) I like my underwear snug, I like a high cut leg with thin sides, I don't like VPL. These passed the test. I could wear these with a lacy bra and you couldn't tell they were wool underwear. Nice thin material, breathable. Looking forward to wearing these all year-round.

Best backpacking underwear
[This review was collected as part of a promotion.] I'm hiking the Colorado trail on a thru-hike and these are the most comfortable, odor resistant underwear. Highly recommend them!

Excellent purchase
[This review was collected as part of a promotion.] I've worn these on several trail runs and am in love. They are so lightweight I forget I'm wearing them. They do offer less coverage than some styles, but I personally like that and appreciate that it's a smaller cut but not a thong. For reference I bought a size small and I'm a 26-27 waist/size 2-4. Five stars, definitely ordering more. And the purple color is beautiful.

Sizes have gotten smaller
[This review was collected as part of a promotion.] I've bought the same underwear in the past same size and this time around it appears the measurements have at least an inch missing in fabric/waistband compared to my other size small.

Fantastic
[This review was collected as part of a promotion.] If you're on the fence about these, go for it. They're so light and comfy, and very flattering. They are a little low cut, so if you're between sizes I'd size up. These are so much better than the competition I've tried, it's not even a contest.

A lifelong customer
[This review was collected as part of a promotion.] Ice breaker underwear are by far my favorite. They are soft and breathable. They meet the needs of an active lifestyle. They aren't necessarily as durable as cotton but I feel good about the material sourcing.
