This Spacer bra is one small step for woman, one huge step towards a lighter-than-air everyday bra. Featuring cups molded out of a cutting edge spacer fabric, this bra has the smoothness of your standard molded t-shirt bra, but a fraction of the weight. It offers firm support, but is so sheer you can juuuust see through it when you hold it up to the light. OnGossamer's signature mesh at the center gore and band truly make this a space-age basic. Sheer bliss from an A to a DD.
