What do you give a sweaty water bottle on a hot summer day?

A sweater, of course. One made of wool is even better. Wool can absorb condensation off the bottle without becoming soaked—unless of course your bottle perspires like a couch potato in a Tae Bo class. Only the cable pattern cascades down the sides of the cozy, on the front and back panels.

But the cozy itself is knit from the bottom up and was originally designed for a rectangular bottle. But, if your bottle is round and approximately ten inches in diameter, this cozy can work for it, too.
