Insulated Flip Lid Tumblers: Cold Hot Coffee compared... Leak-Proof Tested!

We’ve put our new insulated tumblers to the test, measuring both cold and hot coffee performance. The 12oz and 17oz options have impressed us with their sleek stainless steel design and vacuum insulation. Our morning latte stayed hot for hours, even after a rigorous commute, while an iced coffee remained refreshing throughout the afternoon. The flip lid is a standout feature—secure and simple to use, it’s been entirely leak-proof so far. We appreciate the versatility, perfect for busy mornings or long hikes. These mugs strike the ideal balance between style and functionality, keeping beverages just how we like them. Whether we’re simplifying our routine or exploring new flavors, these tumblers have become a go-to for both cold and hot adventures.
