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.

This T-shirt is praised for its perfect fit, high-quality craftsmanship, and elegant neckline, making it a great lightweight base layer for everyday comfort and layering. However, opinions on the material and sizing vary, with some finding it thin and see-through, while others recommend sizing up.

"I am 5’2” and 105 lbs. I ordered XS in black and am happy with the size and really like the look. It is fitted, but not too tight and the length is good for me. Can be dressed up or down. Easy to handwash. What I don’t like is the large and bulky tags on the inside. Very irritating for a fitted top. Icebreaker, please make tops without the large tags!"

"I normally wear an XS in the 200 weight, but the 150 is a little sheer, so I will size up for my next t shirt."
— Tabitha F. (5/5)
"Perfect fit and weight!"
— Julie G. (5/5)
"I love the color and quality of this wool blend T-shirt. The neckline is elegant and the length is nice. I only gave one less star because the shirt runs quite tight and I would have preferred a slightly looser fit."
— AJB (4/5)
"This is my second one. I wear it for sports, as an undershirt or even as a pyjama top. Love it! My only tiny complaint is the tags sewn into the seam. Tricky to remove but necessary for comfort."
— LoLo (5/5)
"I use this shirt for Hiking. It's cool in the summer and comfortable. I don't know how it works, but somehow it keeps the sweat from getting stinky. One thing you need to know about this brand is you have to wash it on gentle setting. Also, I ordered a size bigger than I might ordinarily order cause I didn't want it to be too snug. Large was perfect when medium is usually what I order on other shirts."
— Hiker (5/5)
"Confortable et belle coupe"

"I use it almost daily for all my activities. I love the colour, softness and design."
— Sylwia (5/5)
"Sweet color, soft texture, feels like second skin. Flattering look!"
— Mok (5/5)
"This is my third Siren T, I use them as pyjamas tops. Perfect. The new pink is a lovely bright colour. It makes a change from the recent icebreaker colour palette which feels too earthy and plain for me so I haven't been buying anything for a while."
— Melanie (5/5)
