    Get To Know The Packing Tools

    Compression Packing Cube

    Each backpack includes a compression packing cube made of premium waterproof eco-polyester to help you pack even more.

    The packing cube has 2 compartments, a side for clean clothes and a side for dirty clothes.

    Simply put in your clothes and use the zipper to compress the cube down from 5 ½ inches to 3 ½ inches. Pack all you need in half of the space and save more room for other travel essentials.

    Laundry Bag

    In addition to the compression packing cube, a laundry bag comes with each travel backpack to complete the set.

    You can easily toss dirty clothes in the laundry bag. When the trip is over and the laundry bag is full, it will fit back into your backpack perfectly and keep your dirty clothes separate and organized.

    Shoe Bag

    You can easily fit one pair of shoes. (Up to U.S. size 14)

    Keep your shoes separated from the rest of your clothes & maintain them dust-free.
