A cooler that makes Earth (and you) very happy. Every part of the ECOCOOL Backpack is sustainable! This cooler bag is among the first of its kind to be made with BLOOM™ Rise insulation, an innovative, durable material made from repurposed algae and recycled EVA. Plus, it features a REPREVE® exterior (made from recycled plastic bottles), natural hemp trims and other super cool recyclable details.
