Peak DesignEveryday Backpack 20L Zip, BEDBZ 20 MN 2, Midnight Blue, M

This bag is for run and gun shooters because of its side access but for professionals using this bag might be a hassle. You need to set up your load-out in one side access only and put the other "Not so important" items in the 2nd side access. Also the zipper inside can damage your glass, I don't know why I haven't think about it when I bought this but what I did is, I attach dividers with velcro and place a foam which I removed from the Sigma lens bag/pouch. It is not a clean set up but it is better than damaging my lens. Laptop compartment is a bit tight but it fits my MSI PS63. The dividers will show tear overtime and the rest materials used are good quality.
