Konokyo 1.18 L Insulated Tumbler Water Bottle with Handle and 2-in-1 Straw Lid, Stainless Steel, Double-Wall Vacuum

Konokyo 40 oz Insulated Tumbler is a stainless steel, double-wall vacuum flask with a sturdy handle and dual-function straw lid that keeps drinks cold up to 8 hours and hot up to 6 hours while preventing condensation.

This 40-ounce Konokyo tumbler combines large capacity with a slim-base design so it holds enough water, coffee, or iced drinks to last through long commutes, workouts, or full workdays while still fitting most cup holders. Its 18/8 stainless steel construction and double-wall vacuum insulation minimize temperature transfer and eliminate exterior sweat, while the comfortable handle and non-slip finish make it easy to grip and carry. The included 2-in-1 screw-on lid gives you the choice to sip through a flip spout for hot beverages or use a straw for cold drinks, and extras like a spare straw and seal mean fewer interruptions when you’re on the move.
