Meet our most convenient, travel-friendly cooler bag: The lightweight Packable Puffer. It’s made with recycled polyester from the inside out — including its insulation! — so you can feel good while you chill on the go. Our favorite part: The fully compressible construction lets you scrunch this bag into its own front pocket! That way, when it’s empty, you can easily pack it away or use the included carabiner to attach it to a backpack, bike basket, etc.
