the everything you need all in one place bag

Hi does anyone know what the Velcro patch is for on the side ?

Bought it in May 2021 and three years after already three zips are broken. The first one, on the top it broke almost six months after. It’s ridiculous, it looks like on purpose they are putting poor quality zips to make you buy a new backpack. I have bought nike backpacks since I was at school and by far this one is the worse that I have ever had. It’s a pity that nike has lowered the quality of their products. I used to be a fan of nike products since I was a child but in the last 2-3 years I am really disappointed.
