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

Nice quality and so flattering

"It feels so soft and nice close to the skin. It hugs the body and is very flattering."

— Bella (5/5)

Great top!

"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!"

— Honolulu c. (5/5)

Comfortable base layer

"This is my favorite base layer to wear for extra warmth in cold weather. It is color safe and my older version has held up for several years. Fits true to size. Great for travel because the Merino wool does not hold odors. Should dry overnight if you wash and squeeze the water out with a towel."

— Anonymous (5/5)

I normally wear an XS

"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!

"Perfect fit and weight!"

"Compared to other wool brands Icebreaker holds up better and lasts longer. I wear daily under my work shirt and it helps them last and keeps me from getting stinky in tech shirts! I even machine wash and dry them and they last years."

Nice T-shirt

"I love the neckline and figure hugging fit of this tee. I wear it alone but it would also work great as an undershirt during cooler months. The feel isn't as silky soft as some of my other Icebreaker clothing but I don't find it itchy at all."

— Anonymous (5/5)

This shirt is so pretty and high quality

"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."

Soft and practical, I love it.

"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)
