I'm looking for an winter bag and i'm loving the damier speedy. I alreay have the 25 in mono so iwould like a thirty now. I've made some pictures of the stuff that i always carry (yess is smoke i'm really stupid) + keys that are not pictured. Sometimes i carry a bit more like a bottle of water and i might get a small umbrella (they have really cute ones at H&M right now). I put a cardbord in my 25 to prevent it from sagging because i don't really like it. Do you think i carry enough stuff to use a speedy 30 and would be able to prevent the sag a little? Thanks.
