Each one of these Birdie Bags keeps 10 plastic bottles out of the landfill! Our new Heavyweight Poly material contains 100% post-consumer recycled materials (RPET). This eco-friendly utility fabric has a heavier hand feel, is more durable, and is made consciously. This means you don't have to sacrifice style for functionality. Meet 4CP RPET Birdie Bag, our whatever-you-want-it-to-be tote. With a sizeable gusset, this tote can handle just about anything, and with exterior gussets, it is bound to stand out. Groceries, library books, or beach supplies, it's quite the versatile tote.
