A couple months back I was sent a Geigerrig Rig 500 Hydration Pack to see if the pack really lives up to some of the things that I have heard about it. I was amazed at how much publicity Geigerrig has been getting and how strong some people’s opinions have been when commenting on reviews of the Geigerrig. I thought if people really have these strong of opinions about the Geigerrig, there must be something to it.
