Okay, let’s talk about the Owala SmoothSip. I’ve been using this one for a few weeks, and it’s quickly become my go-to for my morning commute.
The biggest win for me is the true ceramic-coated interior. You know how stainless steel can sometimes give your coffee a weird metallic tang?
None of that here. It’s just the pure, clean taste of your brew, which is a game-changer.
The SmoothSip Slider spout is also thoughtfully designed; it feels really natural to drink from and, more importantly, it’s completely leak-proof. I’ve tossed this in my bag without a second thought, and not a single drop has escaped.
It’s perfect for anyone who’s always on the move and can’t stand that metallic aftertaste. The only real bummer is that while the lid is dishwasher-safe, the cup itself is hand-wash only.
It’s a small trade-off for keeping that ceramic lining in perfect shape, but definitely something to consider if you hate doing dishes.

RTIC 20oz Essential Tumbler with Lid

I’ve been on the hunt for a larger tumbler that doesn’t make my morning coffee taste like I’m licking a penny, and this RTIC really delivers. The magic is in its ceramic-lined interior, which completely gets rid of that weird metallic tang you get from standard stainless steel mugs.
It keeps my coffee genuinely hot for my entire morning, easily hitting the 6-hour mark. With a generous 20oz capacity, it’s perfect for those of us who need a serious amount of caffeine to get going or want a single container for the whole workday.
This is the ideal tumbler for a commuter who relies on their car’s cupholder or for your desk at the office. The one thing to be mindful of is the lid.
While the leak-resistant lid is great for preventing splashes on a bumpy road, it’s not fully leak-proof. If you knock it over, you’re going to have a spill, so I wouldn’t toss it in a backpack.
✓ Reasons to Buy
- The ceramic lining preserves your drink’s pure flavor.
- A large 20-ounce capacity holds plenty of coffee.
- Its no-sweat exterior keeps your hands dry.
- The double-wall insulation works exceptionally well.
- It has a very sturdy and durable construction.
✗ Reasons Not to Buy
- The lid is not completely leak-proof when tipped.
- Only the lid is top-rack dishwasher safe.
- Its size can be too wide for some cupholders.

If you’re tired of coffee mugs that promise no spills but deliver big messes, you need to meet the Owala SmoothSip. I can confidently say its completely leak-proof lid is the real deal.
I’ve turned it upside down in my bag without a single drop escaping, which is a total game-changer for my chaotic commute. The drinking experience is also top-notch; the SmoothSip Slider spout feels really natural and comfortable, and the ceramic lining means your coffee tastes like coffee, period.
This is the perfect tumbler for anyone who needs to throw their mug in a bag and go—students, public transit riders, or just clumsy people like me. The main trade-off you make for this portability and perfect seal is the size.
The 12-ounce capacity is basically a standard home coffee cup, so if you’re used to a giant Venti-sized drink, you’ll find yourself heading for a refill pretty quickly. But for a perfect, worry-free cup, it’s fantastic.

FAQs
Which tumbler is truly leak-proof for carrying in a bag?
The Owala SmoothSip Slider is the better choice for a truly leak-proof experience, as its slide-top lid is designed to seal completely when closed. While the RTIC 20oz Essential is excellent at preventing splashes during a commute, its press-in lid is more splash-resistant than fully leak-proof, making the Owala safer to toss in a bag.
How does the drinking experience of the Owala compare to the RTIC?
Both tumblers successfully eliminate metallic taste with their ceramic interiors. The primary difference is the mouthpiece; the Owala SmoothSip Slider features a uniquely shaped, smooth-edged spout that provides a very comfortable sipping feel. The RTIC 20oz Essential has a more traditional lid opening, so the choice comes down to personal preference for that sipping detail.
Why choose a ceramic-lined tumbler over a standard stainless steel one?
The main reason is taste preservation. The inert ceramic lining prevents the metallic taste that stainless steel can impart on drinks, especially acidic ones like coffee. This gives you the pure flavor of your beverage while still benefiting from the durability and excellent temperature insulation of a stainless steel body.
How should I care for my ceramic-lined tumbler to ensure it lasts?
Always hand-wash the tumbler with a soft sponge and gentle soap, as abrasive scrubbers or the dishwasher can damage the ceramic lining over time. Be careful not to drop it, as a hard impact can crack the interior ceramic even if the outer steel body appears undamaged. Most lids are also best cleaned by hand to protect their seals.
Does the 12oz Owala SmoothSip Slider work for most coffee drinkers?
The 12oz Owala SmoothSip Slider is perfect if you typically drink a standard 8-10 ounce cup of coffee or use a single-serve machine like a Keurig. It’s compact and fits under most brewers easily. If you prefer larger lattes or want your drink to last all morning, you should opt for the 20oz version.
Beyond the ceramic, what’s the most important feature to consider?
Pay close attention to the lid design and how easy it is to clean. Lids with complex mechanisms or tight, non-removable parts can be difficult to clean thoroughly and can trap old coffee residue. A simple lid that can be fully disassembled is far more hygienic and easier to maintain in the long run.
Does the ceramic lining affect the tumbler’s ability to keep drinks hot?
No, the heat retention is determined by the double-wall vacuum insulation of the stainless steel body, not the ceramic lining. The ceramic is a very thin layer that doesn’t impact the insulation performance. A ceramic-lined tumbler will keep your coffee hot for just as long as a comparable all-stainless steel model.
