Keith Double Wall Titanium Mug with Lid 450 ml

The Keith Double Wall Titanium Mug with Lid is a 450 ml titanium mug with an insulating air gap between its two walls, keeping hot drinks hot and cold drinks cold longer than a single-wall cup. It measures 88 mm in diameter and 98 mm tall, sized for a proper mug of tea or coffee rather than a sipping cup. The mug alone weighs 115 g, with the lid adding 29 g for a combined 144 g. Titanium construction means it will not dent like aluminium or rust like steel, and it takes direct heat from a stove if needed, though the double wall is built for insulation rather than fast boiling. The lid keeps drinks warm longer and stops spills in a pack, making this a mug for camp mornings and evenings rather than an ultralight minimalist's single-wall cup — the double wall and lid add weight that a gram-counter carrying just a simple cup would skip.
