We’ve all done it, after a long day you leave your Camelbak laying about somewhere and forget about it until your next hike. When that next hike rolls around something’s growing in your pack’s bladder that most likey should be sent into a research lab for study. In such a case, toss the Camelbak’s Cleaning Tablet’s into the bladder, twiddle your thumbs for five minutes and voila! you’re good to go. No more mildew, stale tasting, green object floating water!
