Let me say this about bundle wrapping: It works. It works very well. On my last trip I made a more serious effort than ever to exactly follow the instructions from the Red Oxx website (in the form of a diagram based on Doug Dyment’s method.) I was astounded at how well the bundle system prevented wrinkles in my cotton and cotton-blend clothing. Click on the bottom photo below for an image file which explains the system. Better yet, download the PDF from the Red Oxx site, print it, laminate it, and tuck it in your bag. You’ll be glad you did.
This method can be used in bags with or without hold-down straps and with or without packing cubes. The bundle helps keep everything together which decreases the need for hold-downs if the bag is snug and tightly packed . I believe I got better results in an undersized bag without hold-down straps than I ever did with the straps. Why does it work? Read Doug Dyment’s explanation here.
