Cuben takeover

[NCPatrick]

Something else about those light green cuben sacks, I decided to test one's strength one day by holding it open with one hand and punching the bottom of it repeatedly with the other. I was beatin the crap out of it and never came close to ripping or unthreading anything.
You can grab it and do your best to tear it and it doesn't budge.

That's the lightweight stuff, so you know the heavy stuff is pretty much bomb proof.

Maybe they only rip when you DON'T want them to?

I would be more worried about sharp rocks or sticks or smaller sharp things...
