The Thermos Insulated mobile mug 500 ml is a stainless steel, double-wall vacuum-insulated travel mug built for drinking on the move — in the car, on a bike, or on the trail. The push-pull spout lets you drink one-handed without unscrewing a cap, and the mug's dimensions are sized to fit standard car cup holders.
Insulation keeps drinks hot for 16 hours, staying above 68°C even after 6 hours from filling — meaning a morning coffee or tea is still genuinely hot well into the day. Cold drinks stay cold for up to 18 hours, making the mug a reasonable year-round option rather than a summer- or winter-only piece.
At 500 ml and 210 g, it strikes a middle ground between capacity and portability — bigger than a compact pocket mug, so it holds enough for a full morning, but still light enough to clip to a pack side pocket or bike bag. The stainless steel build is rated for hot liquids and is BPA-free.
