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.

Great underwear!

I love icebreaker underwear. It’s all I wear anymore! It’s wicking and less odor than other fabrics. Perfect for everyday wear or backpacking. I personally prefer the fit of the hipkini over these, but still a great choice.

Winner

I've tried many styles and a few different brands for wool undies, these are by far my favorite so far. No tight seams digging into your bum cheeks. I'm 5'5" 130 lbs athletic (size 2 in jeans) and the smalls and mediums of these both fit (the medium fits better).

I never thought I would buy wool underwear but a coworker of mine recommended them. I like the fit and their softness and wicking capabilities. Unfortunately I was a little let down by the odor control - I had thought it would be better. Overall, glad I purchased.

My favorite undies

[This review was collected as part of a promotion.] I started to solely convert to wool undies a few years ago because they're far more durable, easy to sink wash on vacation, and much less likely to get icky on long backpacking trips when no sinks are around. Icebreakers are my favorite - they've held up to the test of time and the elastic bits have stayed tight (unlike my Smartwool undies which have become saggy over time). Highly recommend!

Runs REALLY small

Run quite small. I will still wear it, but I wish it were less skimpy on the fabric.

Favorite undies

[This review was collected as part of a promotion.] This was a second purchase because these are the best undies I've ever had. They are comfortable for every day and great for overnight backpacking as they dry quickly and stay relatively fresh. Highly recommend!

Not sure what changed

[This review was collected as part of a promotion.] I've bought this type of underwear in the same size previously, but for some reason, this time they did not fit well at all. It wasn't even the waistband, just how they sat on my body. Uncomfortable!
