Hydro Flask 24 oz Standard Mouth review

The Hydro Flask 24 oz Standard Mouth ranks third because it has the most balanced insulation figures in a size that still fits a car or airplane cupholder. Hydro Flask says it keeps cold drinks cold for 24 hours and hot drinks hot for up to 12 hours, the longest hot claim among bottles here that publish one. TempShield double-wall vacuum insulation does the work, the bottle is leakproof when closed, and Hydro Flask says it won't retain odor or leftover flavor, which helps if you switch between coffee and water. It is dishwasher safe and BPA-free, and it takes the Standard Mouth Flex Cap and Flex Straw Cap. The price is $39.95. The trade-offs: it costs about twice as much as the CamelBak Chute Mag on sale, it is not meant for carbonated drinks, and the page we read lists no weight. We compared documented features and published prices and did not test the bottle.
