Reviews

Love these and they wash so well

"Icebreaker make fabulous underwear will never go back to cotton. Love the colour, hoping to get a bra to match"

— Zozz (5/5)

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."
