Great bag! It's pretty much the maximum allowed dimensions for a checked bag. Much bigger and you'll get charged a ridiculous oversized luggage fee. There are a bunch of Dakine roller bags about this size, so you've got a couple choices in this range. We packed it FULL of clothes and 2 bottles of definitely-not-tequila on our way back from our mexican adventure and it weighed 49.9 pounds exactly.
I chose this bag for its ability to split into 2 separate checkable bags if it was the only bag my lady and I were going to check but it was too heavy.
The two halves separate completely with 4 giant buckles and a velcro hand-loop at the top. It's got nice big internal compartments, which I liked a lot better than bags that break up the space into 11 different mini-compartments. All I want to do is throw a bunch of clothes in there, I don't need a mini-compartment for my casual underwear and a separate compartment for my formal-dress underwear, thank you very much.
Some reviews said this bag did not stand up well on it's own, and I made sure to pack that end of the bag first so I did not have that problem. I could see that it was possible, but packing that end first did the trick.
All the little details are great. It rolls well, the extendable handle is long enough to lean your carryon backpack over when you're walking around with this rig.
