Waterproof Backpack Manufacturer FAQ

What waterproof rating do JUNYUAN waterproof backpacks have?

The line spans IPX4 to IPX8 ratings per the IEC 60529 standard: IPX4–IPX5 for everyday rain and splash, IPX6 for jets, heavy rain and waves, and IPX7/IPX8 for immersion. Each model is built with heat-welded seams rather than stitched seams, so the seal has no needle holes.

Can I order waterproof backpacks with my own brand logo?
