I normally wear an A cup, so bras like this usually work fine for me. Since I love almost everything Patagonia makes, I decided to try this bra. I ordered the size small. The band fit fine, but the cup size was indeed "tiny". I looked like a C cup trying to fit in an A cup bra. This might be a good pre-teen bra, and it might work for AA cup and smaller, but if you don't fit either of those categories, I recommend you skip this one.

This bra is extremely comfortable if you size it correctly. I find the sizing chart to be somewhat off, in that I am a size 38 A (perhaps even a AA), but need a large to keep from feeling confined. The cup size does not increase much (if at all) from Small to Large, so this bra probably won't fit anyone larger than a B cup comfortably. I have worn this bra both at work and while climbing. It offers a rather large range of movement, without any discomfort or bunching. Overall, it’s a fantastic bra.

It is very binding for me, hurts my back after awhile.

I love this bra.

After taking a look at myself after a 5 K run in the "Active Tiny Bra" I noticed that not only did I look as the bra indicated in its name, but also saggy. Great amusement was had by all my friends; however, I will not be revisiting those pictures in a "wow, I really loooked great" moment. Felt great but didn't look so hot.

If you are married to a ballerina or a 32:00 10K runner, this is the bra for her. I bought my wife one and gave it to her on our honeymoon. Since then I have bought two more. She says there is nothing, nothing out there that comes close in comfort. Buyer beware, they go fast and most sites can't keep them in stock. If you find it here, buy it now and save it for when you get in the doghouse.

This bra is so perfect for those of us who just need a tiny bra. With adjustable straps, it allows for changing the size for comfort and movement. Now my favorite bra...

Quite comfortable, does not rub under arms. I like the tiny straps and flat back that do not bulge thru the shirt! Lightweight and small, making it easy to pack for travel. Good for casual wear, not exercise as there is not enough support. I plan to order in black.

The nice thing about this bra is the elastic support band. It's really soft and comfortable and doesn't cut into my skin like the shelf bras in most camisoles.
