The lightweight GRID system uses compression to immobilize and compartmentalize your gear, firmly holding it in place and providing advanced protection during transport. The result is less movement and better impact resistance for your gear than you'll get from current open cell foam options that can let your gear slide around inside your case during transport. Also, the GRID's EPP make up doesn't absorb contaminants like open cell foam does, providing resistance to liquid and chemical intrusion and mitigating contamination of your gear. Cleaning up dirt, chemicals, and liquids is easy with just a damp cloth. Offering numerous advantages over traditional foam and expensive laser-cut inserts, the GRID provides intuitive, modular organization at your fingertips. It's reconfigurable without tools, so it can be adapted to your loadout in seconds. If you're carrying wider or taller equipment, a center GRID Panel can also be removed to open up space for objects approximately 4.25" inches wide. If you end up needing to cut a Panel to create a unique cavity for wider gear, the EPP cuts smoothly and doesn't lose its strength or ability to protect your important equipment.
