Flex Sip Coffee Tumbler (20oz)
8.5/ 10

Why we love it

Hydro Flask's coffee bottle holds 20oz, keeps it hot up to 12 hours by Hydro Flask's rating, and its Flex Sip lid twists shut leakproof for the bag. It fits most cupholders, and the stainless steel interior doesn't carry yesterday's coffee into today's, per Hydro Flask. The whole thing, lid and bottle, goes in the dishwasher, which most travel mugs can't say.

Pros

  • 20oz, hot up to 12 hours, per Hydro Flask
  • Flex Sip lid is leakproof when closed
  • Lid and bottle both dishwasher safe
  • Fits most cupholders

Cons

  • Twist lid is slower than a push-button
  • Not as narrow as a 16oz mug
  • Sip opening is small for adding milk
