I picked up a Mystery Ranch Shift Plus backpack at a pawn shop for 80.00$ to turn it into a first-aid, road side emergency/rescue bag for my vehicle. Road flares, seat belt cutter, etc. Anyone have experience with these packs, seams very well built. I liked the design of this pack, is what caught my eye, because it did not look like a regular backpack, but more like a gear bag with shoulder straps to me. Just curious, thanks.
