If you are planning for a wilderness experience in rainy season then carry some plastic bags with you. They will help in protecting your matchboxes along with all your electronic equipments such as lead lamp or mobile phones.
Great but I think that it will depend on the person that how much weight he/she can carry. The idea of putting the things in pockets is good. Besides if I am creating the survival kit then firstly I will pick first aid box and eatables. Then the other things like battery, fuel and others.
