I have to disagree with the 2 reviews below me. I've used this bra for the last 2 summers as a base layer to go under my yellow nomex while wildland fire fighing and I couldn't be more pleased with it.

You are probably thinking wool? For a bra?? Yes. It keeps you from smelling and its keeps you cool and dry. The fibers in merino are different than normal wool so it isn't itchy like your favorite holiday sweater.

True to size, comfortable, and moves with me without having to be readjusted. I have lived in this bra nearly every day for around 10 months (counting both fire seasons) and it has yet to start breaking down or show any wear.

I typically work in conditions that very hot, both in radiant heat and weather and I sweat A LOT. The merino wool keeps me from getting hot and drenched in sweat as it wicks away moisture from sweat and pulls it to the outer most layer so it can evaporate.

In summary this is an awesome piece and Icebreaker is an outstanding brand that makes quality products.

Sweaty, too hot for summer

I generally wear a 34 A, bought a medium, and it looked really cute on. I bought it for spring and summer backpacking, but it turned out to be too thick and heavy of a material for me to use during aerobic and sweaty activities. It does not stretch much, which I think is probably good for high impact activities, but this feature also makes it really difficult to take off by yourself. Especially if you have anything nearing broad shoulders like I do. It was surprising for it to be so hard to take off even though I sized up from my usual small. I find it is ok for slow yoga and ice skating, but would not wear this backpacking again.


Runs small, feels itchy

First, if you're tempted to try this item, definitely size up. I almost always wear an XS on top (including w/other Icebreaker items), but I could barely breathe in this XS. The S fit better, but I couldn't get past the itch factor -- again, not usually a problem with Icebreaker items. So, returning this one, unfortunately.


Lovely, but not for me

The quality of this bra is fantastic, nice feeling wool and well made. Unfortunately it did not work for me. I had hoped to find a wool bra to work for my D cups and this bra was one of the only ones that claims to work for D cup sizes (light support). It didn't feel right on me-- it felt like I would burst out of it. I think this would be great for smaller cup sizes.
