The Contigo Luxe Stainless Steel Travel Mug with AUTOSEAL Lid Stainless Steel, 16 fl oz. combines the convenience of drinks that stay hot or cold for hours with an elevated metallic finish sure to get noticed. Plus, the lid’s push-button AUTOSEAL technology seals when you’re done sipping, making the mug 100% spill-proof for confidence against messy spills on the go. The lid can be locked when not in use to ensure the button isn’t pressed accidentally in transit. THERMALOCK stainless steel double-wall vacuum insulation means drinks stay hot up to 5 hours or cold up to 12. At the end of a long day, you’ll appreciate that the underside of the lid opens up for easier, more thorough cleaning and both lid and body are top-rack dishwasher safe.
