Very lightweight bra

[This review was collected as part of a promotion.] Bought this for summer. It's very lightweight and low support, but comfortable. The band is very stretchy, but xs is a little too small for my normal 32-34in band. The cup inserts are nice and gives a good shape.

I love the neutral color

[This review was collected as part of a promotion.] Quite a solid bra, good cut. Very nice, neutral color. I can wear it not only to the gym. Unfortunately, it's not 100% merino and the threads are polyester. It's good that the pads are removable. Who even wears these kinds of things anymore?

Quite a solid bra

[This review was collected as part of a promotion.] Quite a solid bra, good cut. I bought the matching underwear and intend to use them as a swimsuit. Very nice color. Unfortunately, it's not 100% merino and the threads are polyester. It's good that the pads are removable. Who even wears these kinds of things anymore?

obnoxious labeling

[This review was collected as part of a promotion.] I enjoy Icebreaker merino clothing, but at least for the under garments can you please make the tags removable... As for the item itself, the band is a bit snug but tolerable, making it great for sports but not as much for casual wear. Otherwise a great piece.

A great one.

[This review was collected as part of a promotion.] Durable. It's my second bra. Very soft and no extra fabric confining me.

Too small

Based on the size chart, I'm a medium (36A). However, the band was uncomfortably tight. The cups weren't exactly small, but they don't cover enough. And they smash. I don't usually have cleavage, but I sure do in this bra.

Nice bra

[This review was collected as part of a promotion.] I always wear the Icebreaker sports bra. I thought I would give this style a try. It fits well, and I plan to take it traveling for hand washing in hotel sinks, and always dry by morning.

Not enough support for a my 34D frame.

[This review was collected as part of a promotion.] I'm 5'-3", 135 lbs, 34D. I purchased a medium and it barely held my girls together. Perhaps I bought the incorrect size and needed to size up, but the band wasn't thick enough so I returned it. I have other Merino wool bralettes that are more supportive.

I love this bra for travel and every day

[This review was collected as part of a promotion.] This is my third siren bra but not because they aren't well made- they are! My first (medium in a blush color) became a bit too small so I ordered a large in black. It was perfect so I just ordered this flesh tone one. I do wish the straps were wider, so it's 4.5 stars not 5. I can wear one day after day in hot, humid weather and always feel comfortable. They do get damp (no odor) when hiking in the mountains in hot weather but are dry by morning. On a long hiking day I used it and my queen briefs as a swimsuit and was as covered as any two piece I've owned. I never want to wear my other bras now and when I travel for 3-6 weeks, I wear one and pack one and that's one more than I really need.

I followed the sizing chart but the bra cup is too big

[This review was collected as part of a promotion.] I'm sad. I am a 36A. According to the size chart, I am an L. So I ordered not one but two size L bras. So much room in the cup area I feel I need to stuff my bra like I did in 8th grade. I should have bought a size Medium. Alas, I cannot return these items for a smaller size.
