Weather-sealed 45-liter rear cargo box with a gasket lid and a lockable latch. Mounts to standard racks or a factory cargo channel.
Bungee-strapping a duffel to the rack works until the first creek crossing. A gasketed hard box keeps tools, a first-aid kit, and a spare layer dry, and it locks — which matters at a trailhead parking lot more than most people plan for.
Keep heavy items low and forward in the box. Weight high and far back is what makes a quad feel loose on climbs.
