Perfect for a family of 4
Reviewed by Michelle@CrunchyInTheSuburbs from D.C. Suburbs on Sunday, July 21, 2013
This hauler is perfect for our family! Everyone gets a cube, and what fits, we take, what doesn't fit, gets left behind. Helps keep us from overpacking for trips. Initially we were sent the four cube things but the gray hauler case was the one that went with the modular hauler 3, but Sierra Trading ... Read More

  • Love them but....
    Verified Buyer Reviewed by ymnovak from California on Monday, October 22, 2018
    They are great versitile bags, the only problem with them is that the are floppy, as there is nothing inside them to hold them up. So I purchased a small rubbermaid tray (15X6) to fit in the bottom of them to give it more of a form. They truly are a great product, just wish there was something already built in for creating a more usable bag, especially for camping etc.
  • Great storage, needs more structure
    Verified Buyer Reviewed by Palmtree2104 from Northern California on Thursday, August 9, 2018
    I like the size of these cubes and the holder, but I thought it would be hardsided to make putting/taking the cubes in/out easier.
  • Quality less
    Verified Buyer Reviewed by CA outdoor person from California Sierra on Tuesday, August 7, 2018
    What shipped did NOT match the photo and what we thought we'd receive.

    Nice bags, but NOT the same as we bought 5 years ago. They are okay, but a lot cheaper/faster sown design.
  • Great for multiple cars
    Verified Buyer Reviewed by mkmontana from Kalispell, MT on Friday, August 3, 2018
    I switch cars frequently with my husband and this product means I can easily transfer gear from one vehicle to the other without losing or forgetting things. Love the durability and style.
  • Tiny camper
    Reviewed by DiverLori from Ohio on Monday, July 30, 2018
    I just recently purchased a tiny camp which obviously doesn’t have a lot of cabinet storage space, but does have under bench open storage. These Modular Haulers work great. Load up clothes, linens, and kitchenware into the individual cubes and then into the carry bag to the camper, either leave on the bench or floor, or unload the cubes to the under bench storage. All gear has it’s own cube for easy access.
