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

    Ordered the Mountainsmith Modular Hauler 4 to help organize family outings. With our upcoming third annual trip to North Carolina to help celebrate my brothers Copper Barrel Moonshine anniversary, the timing couldn't have been better! We are a family of four and the individual bags are just the right size to pack for a week worth of clothes if packed carefully. I own several Mountainsmith bags and have had good luck with them. The Hauler 4 seems made well enough, I hope to get years of use out of these bags!

    We bought this about 5 years ago for a road trip, and each person in our family of 4 took a different color bag for his or her clothing and personal items. My 15-year-old still uses his bag as his primary suitcase. We were mostly car camping and sometimes staying in hotels. The hauler fit in our cartop carrier (a long narrow one designed for skis). Having our color-coded bags made getting in and out on overnight stops simple. Our bags have plastic tops with clear pockets. These are handy for a packing list, label, etc, or for keeping anything flat that you need easy access to. A couple of things worth noting: first, the handles are attached to the tops of the bags, and this is a weakness. Near the end of the first long trip, my (probably overloaded) bag split along the seam of the lid just above the zipper. This would be very hard to repair as there's not much fabric to work with to reattach the zipper, so that bag is now used for storage. I later found a same-colored, same-sized Mountainsmith bag on sale at an outdoor shop -- and the handles were attached on the sides below the zipper, a much more structurally sound design. So be aware that these bags don't (or may not -- don't know how consistent the product is) have the optimal design for carrying weight, and be careful not to overload -- or if you do, don't lift by the handle alone. Also as others have mentioned, the outer bag does not have any supporting structure, though when loaded it does keep things together. I've used it to corral other sorts of items besides the bags it comes with, such as folding chairs, sleeping bags and pads, tents. It also will fit a couple of cardboard cartons (bankers box or small moving box or apple crate size) and fits nicely in the back of a station wagon, making a secure place to hold grocery bags, etc. Overall we're pleased with the purchase, just a bit disappointed about the broken handle.

    I have three sets. I move from one national park to the other each season. These cubes have replaced all other types of duffle bags, and totes boxes for me. I'm impressed with how much I can put in one cube. I now have 12 cubes and one cooler. I plan to buy another set, just to have on hand.
    I bought my mother and brother a set for Christmas this year.

    Glad to see Sierra Trading Post continues to carry them and Mountainsmith continues to make them.

    The description says "2nds", but I don't see any flaws in the set that I received. It's perfect for what I needed: an organized way to store emergency supplies. I had everything in a big duffel bag, and now I have supplies separated by category so that I can see what what I have and what I need. The hauler is a medium-weight synthetic fabric like a backpack, and the cubes are a similar weight rip-stop fabric; both have what looks like a water-resistant coating inside. They do not have any padding or support, so they do collapse until they're full. I love that the hauler has handles on both ends like a footlocker, because when it is full, it is going to weigh enough so that two people will be needed to carry it.

    We used this for our clothing on a recent camping trip. Although each cube was large enough for a weekend's worth of stuff, it was difficult to get to things without unpacking half of the cube. My next plan is to use the cubes to organize my camp kitchen and miscellaneous camping stuff like lighting. I have put the eating related things such as plates, bowls, silverware, paper products, etc. in one. Another has the cleanup stuff such as a collapsible sink, dishcloths, paper towels, etc. A third has miscellaneous things like flashlights, solar lanterns and charging equipment. Not sure what I will put in the fourth. The carry bag needs two people once it is weighted down but everything folds up very small once contents are removed.
