Made of materials that recycle 14 plastic water bottles per cooler backpack, the Tarana Backpack Cooler is the ideal accessory for the outward-bound environmentalist. This hiking-and-beach-ready cooler bag is ready to explore the planet with you while protecting it too. It's 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.
