Waterproof, lots of space, lift out tray, small compartment in the lid, solid latch, durable. I put my thermos, a few boxes of ammo, flashlight, knife, snack, gloves, hat, heat packs, and sunglasses. That pretty much fills it up, but I don't have to cram it in. It's so much better than tanking a soft bag into the field. I'll probably get another one.
