The Peli Ruck Cases are IP68 rated to keep out dirt, dust, mud, snow, and water. The exterior is a tough ABS plastic with a rubber exoskeleton to dampen drops and knocks. There are multiple exterior lashing points for attaching the cases to backpacks or vehicles.
The lid features a very positive latch so the contents stay safe inside rather than being vomited all over the place, and on the inside there's a flexible lid organizer.
