Other than being made of recycled materials, it doesn't seem that different than other wireless bras. Many wireless bras have stretch to accommodate multiple cup sizes. Also, some of the models on their website look like they would be higher than a C in a properly fitted bra, but if you're just looking for something elastic to cover you without a perfect fit there's already plenty of cheaper options.

I'm also skeptical of whether the recycled materials claim is really that much better. The article and website don't go into it, but how much of bra is recycled? From what? What's the carbon footprint of manufacturing it that way versus another way? Can the bra be recycled when you're done with it?

My impression is that this is just marketing hype.
