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. We've added a touch of LYCRA® for active stretch. The Siren’s sleek design and no-side-seam construction is perfect for everyday comfort and easy layering, while its thin adjustable elastic straps make for a barely-there feel.

The Women's Merino 150 Siren Bra is praised for its comfortable and supportive fit, soft and breathable fabric, and sleek design. However, some customers find the straps too thin and the sizing inconsistent.

"Very nice design! For a lot of tank top, this time just look invisible! Surprisingly easy to wear! was a bit worried it will not be that supportive~ but now I am very tempted to just collect multiple sets of this item!!! and it's underwear!!!"

"Great for hot weather and hot flashes. Pack for recent road trip. Dried fast. Nude color great for white tops. Very comfy."

"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)
"I’ve worn these bras for years and still love them. They last well and are really comfortable. This color is great under white t shirts. This is the first I bought that came with the inserts which I was excited about until I tried it on and found that the inserts are too big for my small cup size, so I don’t use them. Still a fabulous bra."

"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)
"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."

"First time trying a merino Bra. Bought the Praline color (nude color) so it never shown on the outer shirt. The under bust strap feels good, not too tight nor too loose, just right for me. The removable cups are thin but enough to mask the pointedness, especially with a thinT-shirt on. This bra doesn't shaped the breasts but it will be a very comfortable everyday bra."

"Love these bras, I've got several and they've lasted so well. The quality is excellent"

"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."

"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."
