How long will cold drinks stay cold in this 40 oz tumbler?

TempShield® double-wall vacuum insulation minimizes temperature transfer so chilled beverages remain cold for hours under normal conditions. The press-in lid further reduces heat exchange and helps preserve coldness during transport.

• Double-wall vacuum construction for extended chill
• Press-in clear lid reduces air exposure
• Stainless steel interior resists temperature change and odors

Is the lid leak- or splash-resistant and how does the straw work?

The tumbler uses a leak-resistant press-in clear lid paired with a soft, flexible straw that’s easy on teeth and simple to sip from at different angles. While designed to resist leaks and splashes during regular use, it’s not a sealed, flip-lock travel cap, so upright handling is recommended when moving quickly.

• Press-in lid reduces splashing and spills
• Flexible straw for comfortable sipping and versatile angles
• Easy-to-clean components; straw and lid are dishwasher safe
