The 470 ml Stanley AeroLight™ double-walled transit tumbler with vacuum insulation is designed to be lightweight without compromising the desired liquid temperature, keeping drinks hot for 6 hours or cold for 8 hours. The tumbler is leakproof with a locking screw-top lid. This means you do not have to worry about spills as you throw your bottle in your bag and jump on your commuter train or begin your exercise. In addition, the AeroLight™ tumbler is dishwasher safe, and is designed for easy cleaning.
