I love my Snugpak Sleeka, never owned the response, but I want one for my Car kit.
I also have a Maxpedition Lunada that is bombproof. If this is for an EDC bag, go maxpedition if you havent had one yet. If its a car type kit that wont see much action, save the money. My wallet is a Maxpedition Spartan, and looks new after a year of everyday use. So does my Lunada EDC bag for that matter.
