Ok odd question I know. I have a semi-new mono speedy 25 and I LOVE it (I am sure most of you know that by now). I love the size and all but I when I see some 30's I have "sag envy"!! Do any of you have a speedy 25 on the older side - does it sort of loosen up and sag at all? I find myself almost pushing the air out of it when I use it to flatten it up. I am not really a structured-bag type of person but I really do love this bag. Ok.....done with my odd little post! :s
