What makes it a Siren?

The Siren is a lightweight next-to-skin layer. It’s crafted from 150gm merino jersey corespun fabric that’s lighter than most other fabrics we use, and is made with a snug, slim fit that works perfectly as a cosy piece beneath your other layers. Our Siren tees fit tighter than other tees in our range, just size up if you like a looser fit.

Reviews

Attention à la taille

"Magnifique matière. Le bikini ne se sent pas. Le bémol je fais du L et là le Siren en L tombe, glisse sur le bas de mes fesses. C'est ennuyeux. Dommage car je les adore. Je pense recommandé une taille en dessous (au moins)."

— Mélanie G. (3/5)

These are awful. I have

"These are awful. I have probably a dozen pairs of Icebreaker bikini & hipkini briefs. I love their breathability, but have always been frustrated by how quickly they develop holes. This is the worst pair I've had by far (passion color, 150 merino). They developed a number of holes on the first wash."

— Lina H. (1/5)

I purchased the Women’s Merino

"I purchased the Women’s Merino 150 Siren Bikini for my wife, and she absolutely loves them. The merino wool is incredibly soft and breathable—nothing like traditional wool that can feel itchy. They’re lightweight, comfortable, and perfect for everyday wear, whether at home, traveling, or layering for outdoor adventures. She especially appreciates how well they regulate temperature and wick moisture, keeping things fresh throughout the day. The fit is flattering and stays in place without digging in or bunching up. They also wash and wear really well, maintaining their shape and softness over time. Icebreaker has really mastered comfort and practicality with this design. Highly recommended for anyone looking for premium-quality, natural-fiber underwear that feels as good as it performs."

Very comfortable

"Most comfortable underwear ever."

— Ashley (5/5)

My favorite briefs!

"My favorite briefs!"

— Ingrid K. (5/5)

Perfect merino undies!

"I've learned that merino underwear are essential for travel. Unlike cotton underwear that usually don't dry overnight and need assistance of a hair dryer (if available), merino underwear are dry and ready in the morning. We only need to have two pairs-- one to wear, one to wash. I like the fit, comfort, and color of the Siren Bikini."

— Merino F. (5/5)

Featherlight and warm!

Love these undies!

"I love these undies. This is not my first review for them. This color is a little muted, but that's probably a good thing to add to the collection. Highly recommend for fit and comfort— five stars."

— April (5/5)

Best underwear in the world!

"I've been wearing Icebreaker bikini underwear for years and can't imagine ever wearing anything else."

— Goody (5/5)
