Toaks Light Titanium 650ml pot is made of 0.3 mm thin wall titanium, weighing in just 2.8oz (80 g), complete with Toaks' signature lockable-handled lid and gradations in oz and ml. The 650 ml boils 2.75 cups of water—great for solo ultralight backpackers. The pot can contain a 110g fuel canister, a 450 ml cup, or your typical 1-L Nalgene bottle without lid covered (and more below).
