Stop carrying (and paying for) a water bottle AND cooking pot! The Titanium BOT is made to replace both! Half water bottle, half cooking pot, it performs both functions exceptionally well while weighing less than most standard water bottles. It converts easily from a water bottle to a cooking pot with a simple flip of the lid yet its watertight, temperature resistant O-ring won't melt when exposed to heat. The BOT fits in most standard water bottle pockets.
