Testing Wet Backpack Weight: Surprising Results Revealed

https://mountainsforeverybody.com/testing-wet-backpack-weight
I used my two backpacks, one for multi-day tours and one day pack, to check how much heavier they become when wet. It turns out that both gain half a kilogram weight. But for the lighter day pack this implies that it becomes 40% heavier when wet. The larger pack became 24% heavier.

From this I conclude that the main part that gains weight when wet is the harness and hip belt. This means that using a rain cover will not help. So if you want to avoid this extra weight with your heavy pack, perhaps it is best to use a poncho that covers the pack too. But a poncho also adds weight, my own weighs 278 grams.
