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.

"Icebreaker women’s underwear is the most comfortable underwear out there! It’s all I wear. It’s breathable, it doesn’t move around on you and I love the Bikini cut. I highly recommend it for sporting activities and everyday wear. 5 stars"

"This hits RIGHT below my fupa, so it makes me look and feel fat. Gave me low-rise pants flashbacks. It high rise on the butt, so no worries about anything falling out. Took them on a hike in INTENSE humidity, and they were comfortable and good for the hike."
— Tash (3/5)

"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)
"The wool is nice but I still get weggies. I try to use these on high activity days where I’m going to sweat a lot- gym skiiing etc…They are breathable I just prefer a different style."
— Anonymous (4/5)
"I'm a M/L for underwear and bought a large but they don't cover my crack when I'm sitting. Alternated between 2 pairs for a 3 week rafting trip and loved the material but wish fit my butt got quite annoying when rowing."

"This is my favourite underwear. I love that the two pack offers them at a bit of a lower price."
