• Test for Waterproofing: Before relying on your rain cover, test its waterproof capabilities by spraying it with water. This will help you confirm that it provides the protection you need in heavy rain conditions.

Choosing the right size ensures that your bag is fully protected from the elements, while proper securing prevents any unwanted exposure.
