Review: Great - Love that about Hydro Flask. Replace and keep on using their products. This was a replacements for a broken top when I dropped it. Review: No straw included?? - Where’s the straw? You need to attach a straw for this to work properly (otherwise if you just “flip and sip” it leaks like crazy from the little air hole). No mention anywhere that you need your own flexi straw, one was not included. Improper advertising and expensive yet useless product. Not impressed. ## Features - COLD DRINKS FOR 24 HOURS: The honeycomb-insulated Cap keeps beverages at the ideal temperature for hours.
