Will my 25 ever "loosen up" and sag a little?

My Damier Speedy 30 still has one of it's original creases even after 3 mths since i bought it!! I loved the sag too...

I push the air out and flatten the bag, but as it's my "throwing around bag", i flatten it and shove it under the table so that it's squashed between my lap and table when i'm out,.. otherwise, i put it behind my back so that it's squashed between me and the chair... i find that helps with "loosening" the bag. (i told you this bag is for abusing and i love it!!!)

HTH
