I bought this right before the new 4-in-1 came out. I plan to buy it after this sells :) A travel-friendly bag that's also made for everyday use.The ReNew Transit Weekender is fully featured—padded laptop sleeve, two water bottle holders, exterior zip pocket, luggage handle pass-through (that's also a pocket), and multiple ways to carry: crossbody, shoulder, or in-hand. 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. 100% Recycled Polyester with a water-resistant finish, 100% Recycled Polyester Lining Machine Wash Cold.
