It is also important to keep some lightweight cloths handy with you. These clothes include clean underwear, a poncho, a light jacket and a hat. Also, try to keep essential things at your place as per the climate and region. For instance, if you are in an environment that is cold enough, do not forget to keep lightweight blankets for an emergency. On the other hand, if you are in a warm and mosquito-ridden climate, keep bug spray with you, particularly if the bugs in your area have a virus.
