The holes are probably hot cloth drill marks used for marking attachment points for webbing or other details. These are part of the cutting process where multiple layers of fabric is cut and marked for production. The drill holes do not affect the utility of the product in any way.

“Are your backpacks waterproof or do I need to use a rain cover?”
Our most commonly used pack fabric, 1000D Cordura, is water repellant and PU coated on the inside, it is by definition wateproof. Water can however trickle in through seams and stitchlines, so our packs are not 100% waterproof. In heavy rain we recommend using a rain cover.
