The Wine[A]Roo is a pretty purple. It holds 750ml (the standard big bottle size) and can fold up when empty. It would also be good for toting your water about, as some water bottles can be heavy and/or cumbersome.
Whatever you drink from Wine[A]Roo will not taste like plastic. This is a real life, BIG bonus! Just fill up, hide, consume, fold up, go home happy.
The Portable Wine Bag lists for $18.00. But, it sells for $15.00. On Amazon.
