Nylon and PU fabrics require a TPU coating to be completely waterproof.
The IPX6 level can withstand strong water jets (such as heavy rain), and the IPX7 level can allow for short-term immersion (1-meter water depth for 30 minutes). Our backpacks are equipped with a dual waterproofing process (waterproof fabric + pressure-sealing technology) to ensure they are fully sufficient for daily outdoor and water activities.
