These arrived at the mothership a while back. Early samples of Camelbak’s “Elixir” electrolyte tablets.
The production packaging, seen below, is a little more conventional. $10 gets you 12 tablets, each good for 24 ounces of water. The tablets don’t have any sugar in them, so no sticky residue if you’re going to put them in a Camelbak or water bottle or whatnot. Definitely not a bad thing to bring on a summer death march. Nuun has been onto this for a while, too. Their citrus fruit flavor is mighty tasty.
