I figured out how to remove it by watching the video. But after I finish wearing that day, and if I want to store it, is it ok to put the strap and Just put it inside the empty bag (after removing my items) instead of removing? So it's easier?
You don't need to remove it to store it...if you want to unhook the end with the clasp you can roll it up and put it inside the bag with the other end still attached.
