Fit
Slim
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.

Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.
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.
icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.
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.

"I have several of these bras and they are great! I’m a huge fan of wool and they are my every day work bras. Fairly comfortable and low profile, don’t make me feel smashed like sports bras. You can wear them multiple times between washes. I bought this one because all my others were black and needed a nude color under a bridesmaids dress."
— Hannah H. (5/5)
"Perfect nude color for wearing under white clothing. All the benefits of merino. Plan to wear to hot humid locations. Enough support for yoga, day hikes."
— Tree Y. (5/5)
"Love these bras, I've got several and they've lasted so well. The quality is excellent"
— Zozz (5/5)
"I bought and started wearing 4 Siren bras (83% wool, 12% nylon, 5% elastane exclusive of decoration) back in late summer 2023, pretty much wearing them exclusively. Both were at first struggles to put on and take off since the elastic is so tight. Despite my underbust being 31 inches with a full breath in, the XS size’s band was still tight at first but got more comfortable as it loosened. The S size band was more comfortable at first but now that it stretched out, the cups barely cover what I need them to cover. A big plus: I was dramatically more comfortable in hot weather than my family members in more synthetic bras. I especially valued the removable cups and several times thought about writing to the company how I could get more; they were light and thin yet hid pointedness quite well. But overall they and the design of the bra is not going to shape the girls much. After about 2 years of wear, machine wash delicate in mesh bags, and airdry, the adjustable elastic straps started warping, curling, and thus falling down my shoulders and the elastics in the chest band started breaking and poking thru the fabric. Although I’ve still been wearing them for casual situations, I will next try a longer lasting non-elastic band bra."

"The best bra ever! I wear these all the time and have them in so many colors. It's so soft and has the best support for a bralette. I love that they come with padding, so I can either use them or take them out."
— Sofi (5/5)
"I like the bra, but hate the labels. Used to take them out but not this time because they sewed them together with the seam. Come on, is it necessary to have so many labels? They’re so itchy."
— Yu-hui L. (1/5)
"J'ai longtemps hésitée mais je ne suis pas déçue par ce soutien-gorge Siren. Plutôt confortable, le maintien me convient pour un 95 B. La couleur Summit est jolie, la coupe est flatteuse. Je ne mets pas pour l'instant les inserts, quoique assez discrets par leurs épaisseurs, je verrais aux beaux-jours. Je recommande, pour celles qui recherchent un soutien-gorge sans armature pour ses matières naturelles."
— Valérie (5/5)
"I love these bras!! I have them in multiple colors. They are durable and easy to clean. I love that you can wear them multiple times without worrying about odors, perfect for travel."
— Lars (5/5)
"I easily make my bras smell but for this one I had wear it 2 weeks (just doing normal stuff, a little bit of training) before I felt like I should wash it! Just remember that this is not a sport bra because I tried running a bit while wearing this and there is no support. It's fine since there is a sport bra model here."
