The Owala SmoothSip Slider is a 12-ounce double-wall insulated stainless steel coffee tumbler with a slider lid that fully closes between sips. It's built for the use case most travel mugs miss: you can drop it in a tote bag mid-commute, leave it tipped sideways in a car cup holder, and not end up with iced coffee in your laptop sleeve. The slider opens with one thumb so you can drink without unscrewing anything (the brand's gripe with most spill-proof mugs), and the 12 oz size is right for a st
Pros
- Slider lid is fully leakproof, even upside-down in a tote bag
- Fits standard cup holders so it survives the drive AND the desk
- Lid disassembles for deep cleaning, no hidden mold gaskets
Cons
- 12oz refills faster than a standard 16oz Yeti tumbler if you're a multi-cup drinker

Frequently asked questions
Does it actually hold heat as long as a Yeti?
Owala rates it at 5 hours hot, 12 hours cold for double-wall insulation. Real-world testers report hot coffee stays drinkable for about 4 hours, in line with most 12oz tumblers.
Will it fit in a standard cup holder?
Yes. The base is sized for car cup holders and most office desk-mounted holders. The handle does not interfere.
Can I run it through the dishwasher?
The body and lid are top-rack dishwasher safe. The brand recommends disassembling the lid first to clear coffee oils from the slider mechanism.
Does the slider open accidentally in a bag?
The slider has a positive click open and closed, no half positions. Tossing it in a tote bag does not pop the lid open.
