I use these color-coded nylon inserts in my EDC daypack. Red is for trauma, yellow is for survival items, green is for PPE & airway items, and white is for foodstuffs. The less often used inserts are packed lower in the pack. Each insert has a clear vinyl window and hook-side Velcro backing strips. They are no heavier than a similarly sized stuffsack but offer much better access & visualization of contents. At 10.5" x 4" x 2" they fit very naturally in a daypack-sized bag.
