Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.
Merino fibers efficiently manage moisture, absorbing it from your skin and releasing it into the atmosphere. It can absorb up to 35% of its weight in water without feeling wet.
icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.
The thermo-regulation properties of merino wool adapt to your body and external conditions, so you can stay warm in the cold and cool in the heat.

"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."

"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."

"I was hesitant about merino wool at first but have become the biggest fan! Perfect for a hike or everyday wear"
— Ash (5/5)
"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."
— Christina (5/5)
"Tellement confortable. Je ne porte que ce modèle."
— Kim (5/5)
