It's like, the least OP armor attachment in the game.
It doesn't give you more protection, doesn't make you faster, doesn't make your backpack bigger.
It's just makes your repair cost a little bit smaller. But repair cost is always already super small and insignificant, its worth equals one-two expensive items from the Radiation Zone.
This is genuine question because I don't understand those people, i always get kills, take their armor and in 80% of cases they have Nylon Straps on their armor.
