Reusable mugs can often be exposed to dirt and germs - firstly, if carried loose inside a handbag or rucksack but also when handled by baristas or café staff when purchasing drinks. This clever design, however, features a leakproof, flip-top cap that completely covers the mouthpiece when closed, keeping the area your lips touch when drinking much more hygienic. Made from double-wall insulated stainless steel, the mug remains cool to the touch and helps keep drinks hotter for longer*. It also has a leakproof, screw-top lid to prevent spills. Now you can enjoy your favourite drink on-the-go and help reduce the need for single-use plastic cups. Capacity: 340 ml (12 fl. oz). *Than our standard Sipp travel mug.
