The HD series of watertight hard cases by Loaded Gear feature edge-to-edge crushproof protection for storing and transporting equipment. The dual-use design of these protective strong cases is ideal for both protecting valuables during outdoor activities and securing professional equipment for transport. All Loaded Gear HD military cases are designed and manufactured to high military specifications to protect valuable equipment in rugged conditions. The included cubed foam can be customized to tightly form around valuables and electronics, keeping them protected from sudden impact and shock. A watertight o-ring seal keeps sensitive items protected from moisture and water damage, and a pressure equalization valve helps control the internal pressure of the hard case when being transported to different elevations.
