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.

— Zozz (5/5)
"I wanted a wool blend bra for odor resistance and travel, and knew that I loved the Siren line of underwear. I thought maybe it would provide enough support for me (~36 DDD/F) as I'm not picky and tend to prefer wireless/bralette styles, but this particular bra is a little rough, even relative to those standards. My search for a wool bralette continues. The puckering on the cups just below the straps is also a bit of an eye sore, and can show through thin shirts if you tighten the straps to add support. I think, if I was a little smaller, it'd be great! The Siren line is super comfy and great for rinsing off in the sink."

"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."

"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."
