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.

Why choose icebreaker merino wool?

Natural odor resistance
Natural odor resistance

Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.

Moisture management
Moisture management

Merino fibers efficiently manage moisture, absorbing it from your skin and releasing it into the atmosphere. It can absorb up to 35% of its weight in water without feeling wet.

Machine washable
Machine washable

icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.

Temperature regulation
Temperature regulation

The thermo-regulation properties of merino wool adapt to your body and external conditions, so you can stay warm in the cold and cool in the heat.

Reviews

Perfect base layer

"For years I wore uniqlo heat tech shirts, but those would get sweaty and stretch out over time, and I would get too hot in them. This shirt is much nicer on the skin as it never made me sweaty and stays fresh for much longer. I lost my shirt and was devestated—and have since bought a new one. I like that the cut of these shirts are low enough that they’re usually not visible underneath other items, and if I do end up taking a layer off I think the neckline is really beautiful and flattering. I do wish the shirts were a bit longer so they could stay tucked in better. I bought a size small (my usual size, with a chest size of 34b) and it fits well, fitted without being tight."

— Lucia S. (5/5)

Super warm and cosy baselayer

"Great base layer in charcoal. Grey is a little sheer but fine if you wear with a bra underneath. Hugs all the right places."

— Mark (5/5)

Nice top but I do

"Nice top but I do not like it as much as I like the crew neck."

— LORIE R. (4/5)

Perfect for base layering under

"Perfect for base layering under sweaters with low or wide necklines. No visible logo/brand name, which I prefer."

— Alaina M. (5/5)

Comfy and snug

"Comfortable, snug, base layer. Very happy with it."

— Margaret R. (5/5)

Perfect fit and weight

"Perfect fit and weight"

— Julie G. (5/5)

Parfait

"J'adore ce haut. J'en achète 2-3 par an et je les mets autant pour dormir qu'en couche de base. Chandail mince mais qui procure la petite chaleur nécessaire parfaite et qui se met bien sous n'importe quel pull. La coupe est très belle et flatteuse. Je recommande vivement!"

— Moi (5/5)

Superbe!

"Superbe!"

— Lisette L. (5/5)

Disappointment transformed to love

"I was disappointed when this arrived and I realised that I had bought a non 100% wool product. However, I have worn and been won over as it has none of the drawbacks of other mixed products I have worn. Very comfortable and flattering fit. I would not buy a mixed product again (except by mistake) but I am very happy with this top."

— Jean (5/5)

Beautiful cut for a light layer

"This is the first time that I brought an ice breaker product and I am very happy. I bought the heavier weight and this one, and I really like the neck line which is invisible undershirts. It is a very light layer and while it is warm, it's also discreet. You can tell the difference in heat between this and the 260 icebreaker."

— Rosinky (5/5)
