The legacy of Stanley Thermos Mug began in 1913 when American inventor William Stanley Jr. patented the first all-steel vacuum flask, revolutionizing insulated drinkware by replacing fragile glass liners with durable steel. Officially launched in 1915, the brand quickly gained fame for its unrivaled durability, even being tested and used by the U.S. military for its ability to withstand harsh conditions, including being dropped from great heights without damage.

The core of Stanley Thermos Mug’s excellence lies in its innovative craftsmanship. Made of food-grade 18/8 stainless steel (also called 304 stainless steel), it is corrosion-resistant, BPA-free, and safe for daily use. Its double-wall vacuum insulation technology—created by removing air between two steel layers—locks in temperature, keeping hot drinks above 60℃ for 24 hours and cold drinks chilled for up to 120 hours with ice. Many models feature leakproof two-part lids, foldable or retractable handles, and hammered finishes for anti-slip grip and moisture resistance.

Versatile and long-lasting, Stanley Thermos Mugs come in various capacities, suitable for outdoor adventures, office use, or family daily needs. Some designs even function as food jars, capable of stewing eggs or porridge with hot water alone. Upholding the motto of “lasting for generations,” each mug undergoes strict quality checks, embodying the brand’s commitment to durability. Over a century later, Stanley remains a global leader in insulated drinkware, blending its historic innovation with modern practicality to accompany every adventure.
