I want a 5.11 Rush 72 for use as an outdoors go bag. My Mongo is reserved for other uses. I nearly went for a Kodiak but I've really gone off the singe shoulder carry thing. It gets painful after a bit.
I've seen a rush 72 up close.. they are VERY roomy and there are more loops for Molle than on most assault vests... it's a bit bigger tahn my needs tbh but an amazing backpack!
