double insulated cup

Capacities typically range from about 10 ounces up to 40 ounces. Common sizes in this group include 10 oz, 16 oz, 30 oz and 40 oz.

Common lid and drinking options include insulated flip lids, flip-top or drink-thru lids, straw or built-in straw spouts, and multi-position (3-way) lids that let you sip, drink, or use a straw.

Most double-wall cups use vacuum insulation. Some models add a copper-coated inner wall for extra thermal performance, and a few list triple-layer insulation for enhanced retention.

Finishes commonly include powder-coated colorways, gradients, and iridescent/shimmer effects. Many listings emphasize a wide range of colors and specialty coatings.

Bodies are most often stainless steel (commonly specified as 18/8), with lids and trim made from polypropylene and some silicone components. A few descriptions note a copper-coated inner wall and some list recycled stainless steel content.

Some listings highlight the use of post-consumer recycled materials, and others specify recycled stainless steel. Examples in this set include claims such as 90% recycled stainless steel or listings that label the steel as '18/8 recycled stainless steel.'
