I remember Zero bags being a status symbol 20 tears ago. I don't know when it started. I don't know if they still are.

Personally, I find them to be totally impractical because of the ease of damage to aluminum. I laughed when I saw a pax with a Zero bag with a plastic cage/guard around it (not shrink wrap).

To my tastes, they are for show-offs and to me, that is a turn-off.

Sorry.
