A tall cold drink within reach for the whole afternoon

The listing gives one number that matters most: 24+ hours cold, attributed to the maker’s BevGuard insulation. This is a 40 ounce insulated stainless steel tumbler with a handle, a covered straw lid, and a base meant for standard cup holders.

The 24+ hours figure is the manufacturer’s claim for its BevGuard insulation. The listing does not say what ice quantity, starting temperature or room conditions sit behind it, so treat it as a claim stated by the maker rather than a measurement you can plan around. The same goes for 100% leakproof, which describes the SlideSeal lid but comes with no stated test method.

The lid is where the specification gets more concrete. The straw is covered, and the cover slides open or closed. The straw itself is stainless steel with a soft silicone tip, which the listing says reduces the plastic sitting in your water. Every lid component removes for cleaning, and most finishes are dishwasher safe. The listing does not say whether Rose Taupe is among them, so check before you load the machine. For carbonated drinks, it asks for at least 50% ice.

The base is tapered to fit standard cup holders, and the title lists a handle. Weight and exterior dimensions are not given, so the 40 ounce capacity is the only size figure you have. Besides Rose Taupe, it is listed in Lilac Dusk, Prickly Pear and Blue Agave, all 40 ounces.
