Review on Secure Your Gear with Pacsafe 85L Backpack Bag Protector by Lauren Williams

I ordered the 55 liter first to fit in my 24 liter pack and the 55 liter was small so I returned it and got the 85 liter. It will fit perfectly in a 24L backpack (any larger backpack and not an 85L backpack; they vary A LOT in size). After having that in my backpack, I was still able to get stuff out of the backpack and pull out the straps. The lock is a joke too (it can easily be picked in a few minutes; less if you're a career criminal). I wish I could find a cut resistant cable bag that fits over my 24 liter backpack and closes tightly. THEN they would have a solid product (if they included a REAL lock).
