Techno Scorpion 21" Rolling Backpack

Comments about CalPak Techno Scorpion 21" Rolling Backpack:

I bought this backpack for my son who is in 6th grade. He has to carry most of his books with him and this is the biggest backpack I could find, depth wise, and it still isn't big enough. He had a CalPak last year that held up well until the end of the school year when one of the zippers broke but that was okay because he wouldn't be using the backpack during the summer.This backpack he only had for about a month when one of the metal zipper pulls fell off. Fortunately I was able to put it back on or else he would have only been able to open/close the backpack on one side. My husband will need to use pliers to squeeze the metal piece (that the pull hooks on to) tight so that the pull does not fall off again. Also, the plastic/cord pulls are starting to come off.For [$] I'm disappointed in this backpack. The zippers and pulls need more attention to quality and durability. I'm hoping it will hold up for the duration of the school year.I would not buy this backpack again.

the pak has a lot of space,which is nice for school books..Even a lunch bag can fit inside .I almost ordered the 25" , but can see that that would have been way too big. The handle also seems really sturdy . One bad thing was that several of the zipper pulls came off within a week or two .

the only thing that would make this backpack easier to use is larger wheels to hold it up off the snow and slush higher.
