From Website: DESCRIPTION Our most functional, travel-friendly backpack. The ReNew 15" Transit Backpack features a 15" exterior laptop pocket for easy TSA access, catch-all zip pockets for passports and tickets, interior slip pockets for magazines and notebooks, one interior and one exterior water bottle holder, a handy magnetic closure, and a pass-through strap that attaches to rolling luggage. Oh, and it’s made using 100% recycled polyester from recycled plastic bottles.* *The zipper sliders and some of the pulls are metal, but other zipper pulls are recycled polyester. The only new plastic is for the zipper coil (teeth), which is not made from recycled material—yet. Used a handful of times, but it’s too small for me.
