On-the-go cups offer several lid and drinking styles: straw lids, flip-top and drink-through lids, twist-off lids, and multi-mode lids that let you sip or gulp. Some bottles also have push-to-open or locking spouts for a sip-or-swig option.
Care varies by model: many cups and lids are labeled dishwasher-safe, some specify top-rack only, and a few recommend hand-washing the cup while the lid is dishwasher-safe. Follow the product’s care instructions for best results.
Common insulation methods include vacuum insulated double-wall construction, double-wall designs with copper-coated inner walls for extra insulation, and some products that use triple-layer or multi-layer insulation.
Bodies are often stainless steel (commonly labeled 18/8, sometimes recycled 18/8), with silicone and plastics such as polypropylene used for seals and components. Some lids are made from copolyester.
Across these listings, advertised cold retention ranges roughly from about 9 hours up to 40 hours, with examples shown at about 9, 18, 24 and 40 hours.
Double-wall or vacuum-insulated constructions are typically used to handle both hot and cold beverages, and these are often paired with insulated flip lids or other sealed lids.
Portability features often include cup-holder–friendly or narrow bases, built-in handles or comfort grips, and carry loops or handles for easier transport.
