This zippered top closure makes opening and closing your backpack a breeze. It also adds some security and some extra water resistance to the pack. This option still gives you the ability to roll down the top of the pack to reduce the volume of the pack when carrying smaller loads.
We use a #8 YKK Uretek zipper for this application to assure that the zipper will last a long time and will be very water resistant.
We think this option works best with the vertical roll top compression, but it can be used without it as well as you can still clip the buckles to theselves at the top.
This will add about .7oz to the overall pack weight
