I needed a good, reliable everyday backpack for my bike commute to work, and PRVKE EDC so far seems to be perfect for that.
It has great storage options that allow me to carry all my essentials like a laptop, phone, wallet, keys, and also stuff like my backup external HDD and laptop mouse, without obstructing the main storage compartment. All the pockets inside the backpack area are neatly placed above the bottom portion of the main compartment and are made out of nice stretchy mesh material. And the fact that it has a dedicated side laptop pocket as well as another sleeve-type pocket inside the main compartment is just amazing. It allows for so much flexibility when packing.
It works well in rain. I ended up in multiple rainstorms while riding my bike to and back from work, and the items inside never got wet. The outside pockets are well placed and easy to access. The backpack is also very comfortable to wear due to the padded back panel. It feels very secure, like it's glued to your back, but at the same time it does not hinder movement, and sometimes I can barely feel like it is there.
A very well-designed backpack!
