Twenty-two cubic feet is the most we put on a roof. We made it for the move to college, the two-week national park loop and the holiday drive with presents for everybody. It's built the same way as our Everyday bags, with welded seams and flap-covered zippers, just bigger.
Car seats, a stroller and a week of clothes fill a trunk fast. This bag takes the overflow: the bulky, light and awkward stuff.
With this much room, put the heaviest duffels in the center and the pillows on the edges. The car will thank you in crosswinds.
It's best on SUVs, minivans and wagons with a long, wide roof. Compact cars do better with 15 or 16.
It's newer, with around 75 shopper reviews so far.
