For those of you that have the ZPacks Arc Blast backpack, have you had any issues with the vertical Carbon fiber strut coming out at the top unintentionally?
The way the strut is held in place is simply by tension. It's design allows it to be removed from the top by loosening the tension with the lineloc. However, what happened to me was that without touching anything, the strut came out, while hiking, because the material that holds it in place just moved laterally off the strut and allowed it pop through the opening. Once out, getting the strut back in place seems nearly impossible so I am mailing the pack back to ZPacks to have them put back in place and properly tension. Honestly, if it could be permanently tensioned so it couldn't be removed I would be fine with it.
Otherwise, I love the pack, very comfortable and functional.
Any words of wisdom from other Arc Blast users?
