Most durable backpack?

Ever had an experience of taking 500 bullets in the face and being able to withstand it all in heavy survivor armor but your backpack just gets demolished? Its quite annoying, its even destroyed if i have it layered under the suit.

Is there a backpack that can withstand a burst of bullets? I play on android btw so I might not have access to some newer gear.

Survivor backpack, I guess.

I reinforced my survivor rucksack with kevlar, it seems to be less inclined to rip with every single attack now.

Iirc the ripping mechanic works by tearing the piece of clothing when it takes a blow that causes more damage than it’s resistance value. So anything to get those numbers higher will increase resistance to tearing.

That said, a high caliber round will rip just about anything.
