Found these guys online. The Sandpiper Three Day Pass looks perfect. TONS of organization, good size, and well laid-out. However I am wondering about the quality. $60 is in the range of some cheap mass-market brands. I use my bag everyday, it carries my clothes and food, I’m often on foot or on/off public transit, my job requires me to carry PPE and medical supplies. people depend on me and I also use my bags for day or overnight hikes, so they MUST be reliable. anyone have any opinions?

Currently using the 5.11 All Hazards Prime and while it is a good bag, I have minor complaints with it: not enough interior organization, beaver tail kinda floppy unless cinched down. When I was searching for a backpack, my criteria were:
o 1600 cu in +
o At least 2 large “main” pockets
o 1 smaller organization or admin pocket
o Exterior webbing a plus
o Exterior Velcro a plus
o MUST be absolutely bombproof

SO if anyone has any opinions on Sandpiper, or can suggest any other brands, would be appreciated. looking to retire my 511 to ‘grab bag’ duty
