One of the draws for the military aesthetic of some camping equipment is that people equate that look with toughness and quality. I don't know how it is in your country, but here in the US, a lot of the equipment and clothing was manufactured by the lowest cost option, so many civilian options are much, much higher quality than genuine military gear. Also, civilian gear is more general purpose rather than designed for specific equipment.

As a side note, one potential bad thing about using camo gear is that you might encounter people hunting, depending on where you are, and you want to be absolutely certain that they can see you clearly enough to not mistake you for an animal. A noisier pack might actually help drive animals away from you, which might actually be better in the long run depending on what you're wanting to do out there.

I hate to keep blabbing on, but I wanted to recommend the "Ultimate Hiker's Gear Guide: 2nd Edition" by Andrew Skurka. https://www.amazon.com/dp/B01GYPKJ3C/ref=cm_sw_r_cp_awdb_t1_IpvnDbS5XS4N3

A big part of choosing what equipment to buy is knowing what kind of hiking you're wanting to do, and this book does a good job of explaining the different mindsets, and which gear goes best with each one.

Best of luck to you on your hiking journey!
