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.

Disappointed ☹️

Familiarity:
I returned this product before using it

I have another pair of Icebreaker panties and absolutely love them. Like another review said, the grey ones doesn’t come like you see in the picture but with black trimming, not sure why it doesn’t get updated on the site?! Also my pair came with pulled thread, very disappointed in quality, ordered another Icebreaker item and also that one has a flaw((

Ripped with 2 wears

Familiarity:
I've used it once or twice and have initial impressions

The left side ripped from the waistband within 2 wears. The most expensive underwear I've bought, and the least durable.

well constructed

These have a super flattering fit despite being a smaller shape. They didn't dig in anywhere along the hips or tummy area, always a plus when folks get thee waistband design correct. Nicely done!

Good for hot weather

[This review was collected as part of a promotion.] I love these! I was having such an issue with sweat during summer workouts. These wick away the sweat and seem to keep “dry” after a long run. They do run true to size- unfortunately I thought they ran a bit big and my first pair I ordered is a tad too large.

Keeps you dry and comfortable!

[This review was collected as part of a promotion.] The fabric is comfortable and I think it has helped keeps things dry down there, so overall I'm super happy with this product. The only issues I have is that it comes with a giant, thick tag and that the back could be a little wider (it's more prone to wedgies than my other underwear. Not too bad though).

Can’t say enough good things

[This review was collected as part of a promotion.] Honestly, my favorite briefs year in and year out! Great fit. Breathable. Quick dry on the line.

Runs small

[This review was collected as part of a promotion.] The quality feels great so far, but I haven't yet put them to the test on the trail. Surprisingly large tag inside, but can be cut off. Just, the little stub might be irritating. I am only giving 4/5 stars because I used their size guide and measured myself, and I fall under the low end of Small, and yet the Small is WAY too tiny - edges of the bikini dig so deep into the bum cheeks, they look crazy. Try a size up with this product.

Not impressed

So far not impressed. Wore one pair one time and washed in cold once, only to find a good size hole in them. They were comfortable enough but for what they cost I would like to get more than one wear from them.

Really well made, seamless

[This review was collected as part of a promotion.] Thin, seamless, merino wool underwear. All with icebreaker quality. What else would one want?
