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 ☹️

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((

Comfy!

[This review was collected as part of a promotion.] These are very comfy and definitely a good buy! Hoping to replace all my other undies with these.

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

Love this underwear!

I've been wearing this underwear for years. It is comfortable, breathable and resilient. I can wear it for multiple days on the trail and it does not get too dirty or smelly. It also dries fast in open air. I am 5'5", 145 lb and a medium fits me well.

Extra comfortable

(This review was collected as part of a promotion.) Great comfortable underwear. I wouldn’t change a thing about these.

Great breathable hiking underwear

[This review was collected as part of a promotion.] I live in these. No complaints but if you’re a cyclist / bike commuter (and maybe even if you’re not) the front pubic bone area does wear transparent abs you’ll need to replace them regularly. Can’t be best for backpacking though.

Merino pants!

Recently spent 35 days at sea and wore the Merino siren pants (multiple :-))and also had some non merino pants. Without doubt the Icebreaker Merino pants were hands down the winner for comfort, breathability and preventing skin outbreaks.

BEST underwear!

I love these bikinis and have two of every color now. They are so comfortable, like wearing nothing. I have had some pairs for over a year now and there is no sign of wear (no break down in the banding or fabric). I always machine wash and line dry my merino wool stuff.

Forever my brand and style

[This review was collected as part of a promotion.] For the last 7 years I have been wearing these underwear and loving them! I try new ones occasionally, but these are the gold standard. I have pairs that are 7 years old and have held up wonderfully (I hang mine to dry/no fabric softener). I have never had underwear last this long. They are worth every penny!
