These look like cool bags, but now that you've been using it for a bit, how do you find the zippers? - are they taking the strain of your many texts, ledger and lunch?
I'm trying to imagine how, with the back part of the main compartment's pockets full, and the front panel of the main compartment full, that there's room to put in a lunch box (like a tupperware container) or books without stressing the zippers out.
Finally are you happy with the XM or do you wish you'd gotten the bigger xl?
thanks
