Stop carrying a water bottle AND cooking pot - the 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. What it doesn’t fit into is the convention that you can’t have your cake and eat it too. Just another Vargo original idea. BOT Features: Available in both stainless steel or titanium, Screw-top lid with a watertight, heat-resistant O-ring that doubles as a cooking pot lid, and a wide mouth design to make cooking, cleaning, and using a lot easier. It can fit your entire hand inside it while still fitting in most water bottle pockets! 1.0 liter capacity to make measuring, cooking meals, and sterilizing water more convenient. Both pieces work well with pot lifters (sold separately). The BOT also makes a great container for holding a survival kit or food. specifications: Capacity: 1.0 liter (34 oz) Diameter: 4.1 inches (105 mm) Height: 6.3 inches (160 mm) Weight: Titanium BOT - 4.7 ounces (133 grams), Stainless Steel BOT - 8.4 ounces (238 grams).
