FYI- We have the 40 oz. Thermoflasks with the two caps from Costco. We bought the 2-pack 2 years ago and they are as good or better than the more expensive Hyrdoflask, Stanley, etc. We bought more 2-packs to give as gifts for Christmas, birthdays, office gifts etc., and filled them with all kinds of stuff. Everyone loved them. You could do the same with these for a great price. – Hip Reader, acgold


I bought these last year and they have held up beautifully. The size is perfect for keeping track of your fluid consumption. I really love that it has a removable straw, and that you just flip it open to take a drink. You don’t have to twist a cap open, and you don’t have to tilt the bottle. Bonus that it’s dishwasher safe.


These ThermoFlask water bottles are the best I’ve encountered. They are well constructed, durable, ice cubes fit cleanly through the wide opening, and water stays cold for a long time. I use them daily.
