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

So comfortable and breathable

"I procrastinated “splurging”on these for the longest time and they really are worth it. Great for traveling and working out, and they’re sustainably made."

— Al (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)

Favourtie underwear

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

— Ashley (5/5)

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."

— Joshua N. (5/5)

Very comfortable

"Most comfortable underwear ever."

— Ashley (5/5)

If you haven't slipped into

"If you haven't slipped into something this comfortable yet, you are missing out. These are a game changer in life and on the adventure trail."

— Julia C. (5/5)

Best underwear I own

"I love these. They are so breathable and comfortable. I've owned several pairs for over 2 years and they are still like brand new. Machine wash and hang to dry (although i have dried them a few times without skinage, piling or wear). I wear size M and size 30 jeans."

— Nicole F. (5/5)
