I have zero affiliation with these guys, but came across them the other day and wanted to pass this along.
Most ready-made kits are made with cheap Chinese-made dollar store stuff that will fall apart sitting in a closet, let alone being put to any real world use.
This ready-to-rock patrol pack, on the other hand, is built around solid quality, brand name stuff. It comes at an accordingly higher price, but you get really good stuff--a Camelbak HAWG, Leatherman Wave, Fenix Headlamp, QuickClot, Mechanix gloves, etc. Lots of personal favorites there. Impressive.
Maybe a bit light on shelter (comes with a nice Snugpak poncho, though) and you'd probably want to add some ancillaries like cordage, gorilla tape, canteen cup, water filter, but if you are in the market for an off-the-shelf bag, this is the best of I've seen.
One of these would be a great foundation for a cache, too.
