Leak proof flask

Warm drinks while on a long watch add greatly to the pleasure of a passage. Unfortunately, the performance of flasks is often disappointing – many are poorly insulated, are not sufficiently robust, or aren’t ergonomic. From bitter experience I’ve discovered some don’t even seal properly!

These double-wall stainless steel vacuum flasks are intended to solve these issues. They are rated to keep drinks warm for up to 12 hours – or chilled for up to 24 hours – and the cap opens with a single twist. They are available in 280 and 450ml sizes, both of which fit standard cup holders.
