iced coffee tumbler

Iced coffee tumblers commonly range from about 14 oz up to 40 oz. Typical sizes you'll see listed include 14 oz, 20 fl oz (US), 30 oz and 40 oz.

Most tumblers use double-wall or vacuum insulation. Reported cold-retention varies by model — common listings show about 9–11 hours cold on some items, while others claim up to 40 hours (sometimes phrased as “40 hours iced” or “2 days iced”); a few listings note around 18 hours.

Common lid styles include flip-top, twist-off and multi-position screw lids. Drinking options include open drink openings, built-in sip spouts and designs that accept reusable straws or have dedicated straw holes.
