Backpacks are very convenient for travel, especially when they have wheels. This is because you can push them instead of carrying them around. Of course, there is also the possibility that even if your backpack is with wheels, it will still be heavy enough to make hauling it around a chore. Hence, you still have to consider the weight of whatever you are storing in your backpack. It might be best to store items like toiletries or anything that can easily fit into a smaller bag instead of packing them into your large backpack.
