Capacities range from about 13 fl oz up to 36 fl oz. Distinct sizes shown in listings include 13 fl oz, 20 oz, 21 fl oz, 24 oz, 32 oz, and 36 oz.

You’ll find a variety of lids: pop‑up lids and pop‑up straws, straw or flip‑straw lids, flip‑top straw designs, and traditional screw caps as well as sports caps with flip straws.

Many bottles advertise leakproof or spillproof designs, typically using spill‑proof valves on pop‑up straws, leak‑resistant flip‑straw lids, or sealed caps and gaskets to reduce leaks.

Several listings specifically call out 18/8 stainless steel. Some describe the metal as 90% recycled 18/8 stainless steel, while others specify 100% virgin‑sourced 18/8 food‑grade stainless steel.

Listings describe larger drink openings, high‑flow self‑sealing caps, and squeeze‑friendly designs that increase flow and make higher‑volume drinking faster.
