“The GR1 is copied from a Special Forces medic’s bag (you can Google “DA med-pack” or “tactical medic pack” to find used ones on eBay). Med-packs use a mounting system called the MOLLE (Modular Lightweight Load-carrying Equipment) system. Med-packs are covered in MOLLE webbing, inside and out. Medics store and organize their gear in MOLLE pouches with tabs that you thread through the webbing (they also have a Velcro-lined interior to store even more gear).
