Hydro Flask Rocks Tumbler Review

In Drinking Accessory Reviews by Brent JosephLeave a Comment

I was lucky enough to get my hands on one of the new 10 oz rocks tumblers that Hydro Flask is coming out with as part of their new drink ware line releasing on February 1, 2017. The product line includes a 10 oz rocks tumbler, a 22 oz tumbler, and a 32 oz tumbler.

I knew it was only a matter of time before Hydro Flask came out with a line of drink ware to compete with others in the market. There are a few differences between the Hydro Flask and Yeti offerings which I consider the other big player in the stainless vacuum sealed market segment.


1st drink – one large ice cube, half Makers Mark, and half room temp non-carbonated mixer.

33 minutes later – 80% of the ice cube remained.

Refilled with roughly the same amount and another 53 minutes later the second drink is gone, and there is still a chunk of ice roughly the size of a quarter.

I realize that it shouldn’t take me an hour to finish a drink, but I was trying to see how long it would take for the ice to melt in my cocktail. Basically, in my first run, this tumbler kept a large cube for over 90 minutes in two cocktails. Bear in mind this was indoors, but the drink was at least 4-5 oz of room temp Makers Mark. I am sure results will vary a bit depending on the proof of your beverage and the ambient temperature.

After this initial run, I think that once again, Hydro Flask has hit it out of the park and seems to have another great product in their lineup.


  • Standard Hydro Flask Temp Shield technology double walled 18/8 stainless steelInsulated lid (Yeti does not have insulated lids)
  • Easy to grip, and fits perfectly in hand. Would feel right at home at a campsite around a fire pit
  • Available in 5 colors


  • Price, about $10 more than competition at $29.95 MSRP (Includes insulated Lid, also fits 22 oz tumbler)
  • Hand wash only (Lid is dishwasher safe)
  • Lid seals but has a hole for sipping, doesn’t close. (Same as competitors)
