double walled tumbler

Capacities span small kid sizes (around 10 fl oz) through common adult sizes such as 14 oz and 30 oz, up to larger tumblers as big as 40 oz.

Common lid and drinking options include straw lids (with reusable straws), flip-top or drink-through lids, multi-mode lids that let you sip or gulp, push-button or locking lids, and reusable straw-compatible designs.

Most double-walled tumblers use vacuum insulation as the primary construction. Some models add extra layers—examples in listings include a copper-coated insulation layer or triple-layer insulation—to enhance thermal performance.

Common features include handles or comfort grips and a narrower or tapered base designed to fit most car cup holders; many listings explicitly note 'cupholder-compatible.'

Many tumblers include a lid and a reusable straw; some also include a handle or list extras such as straw toppers or ounce markings.

Some listings specify recycled stainless steel (examples cite about 90% recycled stainless steel), and at least one listing mentions post-consumer recycled material. Availability varies by model.
