I was thinking about how much I liked having bottom access to my old Lowe Alpine pack and realized that I haven't seen a UL pack with a bottom access. Zipper would add weight, but I was wondering during class today about adding a roll top style closure to the bottom of a pack. Have you seen something like this before? Thoughts? Ideas?
Thanks.
Green.

Feb 14, 2013 at 5:57 pm #1954524I haven't compared the clips and extra fabric needed to do a roll bottom versus a zipper. I was also thinking about a zipper to make something like a panel loader.
Does anyone have numbers on comparing weight of a zipper versus a roll top? Thanks.
Feb 14, 2013 at 6:09 pm #1954531A roll would almost certainly be heavier than just a zipper. A roll requires not only a certain amount of extra pack fabric, but also a stiffener and closure hardware. But a roll is stronger, more durable, and more water resistant than a zipper, and it affords you some pack volume flexibility. I can think of ways to make a pack with a roll top and roll bottom that opens up into a rectangular sheet (a groundsheet?).
