To reduce this environmental impact, we use a mass pigmentation process that involves adding the colour pigments when the yarn itself is produced.The back mesh of the bag is dyed using mass pigmentation. This dyeing process is called Dope Dyed". 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.
