Crafted from high-quality 18/8 stainless steel, the mug features AeroLight™ double-wall vacuum insulation, which keeps drinks hot for up to 6 hours and cold for up to 8 hours while remaining lightweight and comfortable to carry. The AeroLight technology also makes the tumbler about 33% lighter than standard stainless-steel drinkware, making it ideal for commuting or travel.

The tumbler includes a leak-proof locking lid with a drink-through opening, allowing you to safely carry it in a bag without worrying about spills. Its slim design fits most car cup holders, making it convenient for road trips, office commutes, or everyday errands.

Designed for convenience, the mug is BPA-free and dishwasher safe, ensuring safe drinking and easy cleaning. With its classic black finish, the Stanley AeroLight tumbler offers a timeless, professional look while delivering reliable temperature control and durability for daily use.
