The LXMBP4 consists of four color-coded zipper pouches with clear vinyl window for easing viewing. They can be added to any medical bag, from any brand. Each bag includes an interior pocket and webbing pull loop. The green bag, ideally used for airway items, also features elastic loops for OPA's or nasal airways. Great for mutual aid calls where those assisting may not know the arrangement of your medical bags; just tell them what color bag to give you. This is a set of 4 pouches - Red, Blue, Green and Yellow. Includes a limited lifetime warranty from Lightning X Products.
