Plago 262Liter Professional Quality Nylon Extra Large Duffel Bag Lightweight Foldable Water Resistant Cargo for Travel College Folding Bike Tent Mattress Closet Storage

This was HUGE & I used it to move but could only put lightweight stuff inside or I wouldn’t be able to carry it. It holds SO much, but won’t keep its square shape.

Works well to check a dock-a-tot grande.

The bag is big and strong. It'll enable me to carry more things.
