Once you’ve got everything you need, it’s time to pack them. Make sure you pack the items in your daypack in the right order. Heavy items should be positioned close to the body and around half way up your back. This may also include photo equipment and the food which you’re taking with you. Ideally, but depending on the model, there may be an additional compartment in the lower section of the daypack to store your food. If the heavy items are stowed as close as possible to your body, this will help your posture when walking. It will also relieve back pressure.
Lightweight, chunky items such as a gilet or rain jacket should be placed in the lower part of the backpack. Any items that you are likely to need quickly, such as suntan lotion, mobile phone etc., should be packed last, i.e. stowed at the top or in a top compartment. The water bottle goes in the side pocket so that you can stop for a drink at any stage without firstly having to take off the daypack.
