Our best-selling bra with a comfortable and lightly supportive fit, the Siren Bra features our 150gm jersey corespun fabric, which uses merino wool fibers wrapped around a nylon core for added strength and durability, while retaining next-to-skin softness.

"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)
"Sizing was accurate. Color was what I needed for white summer clothing. Surprisingly comfortable to wear to yoga class, the one time I forgot to pack a sports bra. Not a smooth look under a tight fitting tee. Very light support, not a push up type of bra. Material is perfect for hot sweaty summer weather."

"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."

"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."
