Do you wear a backpack which was in accordance with its function? Because each backpack made by manufactur been designed specifically for a particular situation. For example a bag made for use in different savanna desert terrain with a backpack specially made for use in wet or snow.
Therefore, any material backpack bag will adjust to the allotment was used. This also determine which technologies will be applied in these backpacks. For example a special backpack that has a material used in the savanna backpack customized for a state of "dry" and the application of technologies such as shoulder pads and back will be adjusted to accelerate the evaporation of perspiration and body heat.

So it is with a backpack that will be used in the "wet", usually the manufacturer will make the backpack backpack from waterproof materials. Application of such technology is used to hold the water in order not to enter into a backpack.

In general, each manufacturer has designed a backpack multi-purpose bag, for example by completing a rain cover in the bag. So when the rain arrives, you simply remove the cover from the backpack, then cover with the backpack.

All this is up to you to choose a backpack, but you must know the specification you use a backpack to buy. By knowing a backpack, you can use it optimally. Cheers
