An insulated cooler backpack is pretty cool, but a cooler backpack with a shell made out of 14 recycled water bottles? That?s the Darth Vader Tarana Backpack Cooler, and it?s sustainably cool, which is even better! This hiking-and-beach-ready cooler bag is ready to explore the galaxy with you while helping to protect it too. Pretty thoughtful for a backpack, right? And that?s not the only way it shows a little care and consideration: This lunch cooler bag is comfy to carry thanks to adjustable shoulder straps with a soft mesh underside, features an insulated small cooler with an easy-clean water-resistant liner, AND even packs in an expandable mesh compartment with easy-access drawstring closure. Some people just don?t expect all that much from a backpack, but those people have never met the Darth Vader Tarana Backpack Cooler.
