Skip Hop launched their Go Envi Eco-Friendly Diaper Backpack online. A sporty go-to for mom and dad, the Go Envi Eco-Friendly Diaper Backpack is packed with sustainable style (and lots of extras). Made from recycled plastic bottles, this baby bag is durable, lightweight—and holds a ton. Even better? They tucked a free reusable food tower inside to add to the earth-conscious design.
