steel tumbler

Common capacities include 20 fl oz (US), 24 fl oz (US), 30 oz, 32 fl oz (US), and 40 oz.

Most are made from stainless steel; many listings specifically note 18/8 stainless steel or recycled 18/8 stainless steel construction.

Common lid types include flip-top lids, straw or drink-thru lids (with reusable straws), locking lids (often push-button), multi-position or 3‑in‑1 lids, and proprietary sip‑or‑swig spouts that combine straw and chug openings.

Portability depends on size and base design, but many tumblers are made to fit car cup holders and some listings highlight comfort grips or handles for easier carrying.

Common drinking openings include straw holes with reusable straws, sippable lids, larger drink or chug openings, multi‑position lids that accept a straw or open for drinking, and patented sip‑or‑swig spouts that let you switch between straw sipping and wide‑mouth swigging.
