The NAYAD® Dutton 20oz Vacuum Insulated Tumbler combines bold design with everyday performance. Built with double-wall 18/8 stainless steel construction, it keeps drinks hot or cold for hours without condensation. The screw-on lid with push-button swivel closure delivers a secure, spill-proof seal on the go. A striking square base sets it apart with a modern, unique look that fits most standard cup holders perfectly.
