The bag has a silver-toned finish that's made out of used truck tarps and is paired with a [food-safe insulated liner](https://www.trendhunter.com/trends/dry-bag-sling) to accommodate food and drinks being placed inside. The recycled construction thus gives the accessory a competitive edge for sustainability, while the removable isothermal liner will keep items cool for up to two-hours. The bag also works well as a way to transport chilled items home from the grocery store. The Freitag F738 COOL BAG comes with a detachable shoulder strap crafted out of discarded car seat bels with colorful handles created in collaboration with Precious Plastic Zurich.
