...just like everyone else, the last thing i want to happen when im travelling is to have anything stolen.
My thoughts are that just try and not make my stuff look appealling or different from all the other packs that will be lying around, to be as inconspicuous as possible.
Like CD said, the weight would be one thing to be aware of, and i would just think that maybe having that on you pac may draw unwanted attention to it.
But, also, i would have to agree that if i was a backpack theif, if i saw that on a bag, the last thing i could be bothered doing would be trying to get in through all that mesh.
Soo, yeah, could be a good thing, just not for me is all.
...and if you can make any sense out of this post, your doing better than me.
