The Keith Jug is a flat titanium hip flask machined from grade 1 titanium, shaped to slide into a jacket pocket or a pack's side compartment without bulking out. At 63 g and 120 ml it is one of the lighter flasks on the market — a larger 200 ml Ti9307 variant is also available for anyone who needs more than a few sips.
A titanium screw cap with a seal keeps it leak-proof even carried flat in a pocket, and the included funnel makes filling without spills easier, particularly from a narrow-necked bottle. The flask is BPA-free and food-grade certified, so it works just as well for water or stove fuel as for spirits.
The single-wall, uninsulated build means contents don't stay warm or cold any longer than in an ordinary container — this is a light, durable liquid carrier, not a thermos. There is no carry loop either, so it is meant for a pocket rather than clipping to the outside of a pack.
