Kathy, good planning! May I sugest another pocket option: A well washed, orange cotton bandanna. Give it an intense hot dry ironing and fold it with the iron. Place it immeadiately in a new Gerber Breast Milk Bag and seal. Cover the bag edges with Gorilla Tape. Flat fold an additional meter of Gorilla Tape to about 4 inches. lightly tape the folded G Tape to the bagged bandanna. This gives you an almost sterile bandage/dust mask/signal flag/sucking chest wound, pocket kit that weighs almost nothing. This packet has served me well for years.
