For serious hikers and campers, a great water bottle is important. Even better is a water bottle with a filter built in, but what if your water bottle could handle six different functions in one? It would make your pack a lot lighter and make it on the list of best camping gadgets.
The ÖKO Odyssey water bottle does just that with two filters, a flashlight, a lantern and a storage compartment. The first filter is your standard carbon filter, great for everyday tap water use. The second filter is for when you're away from potable water. It removes bacteria, cysts and other contaminants out of the water -- great for when you're off the beaten path and when you're traveling in countries without reliable access to clean drinking water.
The light adapter also has a strobe function for use as an emergency signal. You can buy the Odyssey for $49.95, which includes all adapters and filters.
