Waterproofing
The backpack has been designed using a fabric that is waterproof up to 2,000 Schmerbers and has 100% taped seams to stop water getting inside. We have chosen a rolling closing system like the one on canyoning backpacks. As such there is no risk of the water going through a zip for example. The "canyon" type fastening is the most effective to stop water from getting inside the bag.
