Ice-cold water
A COLDEST cold water bottle keeps ice for up to 36+ hours* with the Chug or Sports lid closed, and for up to 24+ hours* with the open straw lid on the 36oz and 46oz Limitless. Vicky fills a 46oz with ice to the top, adds water, and three days later still has ice — that is her report, not a published 72-hour test. Susan: ice lasts literally for days. Fill with ice first, top it up with cold water and keep the lid closed. Parked-car heat lives on the hot-car page.

Keep it cold
The cold times above assume these four habits.
1KawanaPack the bottle with ice, then add your drink. A bottle that's mostly water holds its cold for less time than one packed with ice.
Use cold water, not room-temperature water: a warm refill melts the ice faster.
The Chug and Sports lids hold the cold longest. An open straw lid lets some out: up to 24+ hours* instead of up to 36+ hours* on the 36oz and 46oz.
Don't put a COLDEST bottle in the freezer or the microwave. For ice-cold water, fill it with ice and cold water instead.
Why it lasts
From the people who check.
Three walls of pro-grade 18/8 stainless steel with a vacuum between them keep the cold in and the heat out.
