    Bought this with my OverPackBag compression bags and it's the perfect combo. Everything fits, the bag closes easily, and I haven't checked luggage in 6 months.

    Solid build, USB port works great at the airport, and it fits in the overhead bin without any issues. Exactly what I needed for weekend trips

    Love that it opens completely flat, it makes packing the vacuum bags so much easier. Lightweight and feels premium for the price.
