In a world covered by water, humans fight for survival. The polar ice caps have melted, leaving little dry land. Bio-engineered humans have adapted by incorporating gills into their anatomy. This laceweight tank is cool in the wasteland of water and sun, and stylishly accents the gills while allowing ease of movement, while the lace pattern mimics the scales of the fish these aquatic beings swim with.

This pattern is in the book Doomsday Knits, which is currently available at cooperativepress.com, as well as here on Ravelry.
