Designed for life on the move, the Transit Flip Top Mug from Stanley’s Transit Collection features AeroLight spun-steel technology, making it 33% lighter than standard stainless steel drinkware without compromising durability. Double-wall vacuum insulation keeps drinks hot for up to 6 hours, cold for 8 hours, and iced for up to 30 hours, while the leakproof flip-top lid lets you flip open, sip, and lock shut with confidence. Made from 18/8 recycled stainless steel, this BPA-free, dishwasher-safe mug is built for easy cleaning, spill-free travel, and everyday commutes.
