The ECBC Hercules backpack is made of 1000d kodra nylon, and if you know your fabrics (you’re forgiven if you don’t), you’d know that it’s used often in the world of high quality backpacks. It’s both soft and lightweight, yet durable, and is generally water resistant. On this particular backpack, the zippers are water resistant as well. I'm certainly not going to pour liquid on the thing, so I’ll have to take their word for it.
