The Eagle Creek Cross Roads 25 is very versatile. It's quite easy to go from a pulling it as a rolling luggage or carrying it sideways with the side handle to wearing it as a backpack...all you have to do is unzip the back, clip on the shoulder straps, and then close the unzipped part to the bottom of the bag. (Hey, that kinda rhymed...) This bag works well as a rolling luggage. I can't see any problems arising from using it as a rolling luggage. It is also lightweight and comfortable enough to wear around as a backpack for a while, as long as you don't pack too many heavy items in it. It is bulky as a backpack when fully packed, so try to get used to walking around with it before heading out for your trip or you might be bumping into a lot of things. Carrying it sideways is okay as long as you don't pack too heavily. I packed it full of jeans and tried to hold it by the side handle, but it seemed like the handle was gonna rip off so I put it back down. I'm sure it wouldn't have ripped off, because that would be pretty bad designing and manufacturing on Eagle Creek's part. Or maybe it would have ripped off...I don't know and I don't want to be the one to test it out any further. I had one big problem with the bag. The bottle holder on the left side can't really hold a bottle. The side handle gets in the way! Look at the picture and you will see what I am talking about. You could probably use this as a spare pocket, but don't expect to put a bottle in there without it sticking out to the side. Good thing there's a bottle holder on the right side also. All in all, this bag is great and convenient, but I hope Eagle Creek fixes the bottle holder problem and make the bag a little bit more...durable.
