RTIC vs YETI Tumbler (2021): Which Vacuum Insulated Drinkware Is Better?

Comparisons between RTIC and YETI don’t stop with their best-selling adventure coolers. These two brands are at it when it comes to drinkware, too. Like the rest of its catalog, YETI’s insulated tumblers are marketed as premium products. Its YETI Rambler tumblers are arguably the most popular, boasting high-quality construction and varied styles.

RTIC tumblers are designed similarly. The brand’s double-vacuum insulated drinkware claims hours of ice and heat retention, too, but at about half the price of YETI’s. But does it perform as well as its premium rival? Below, we compare RTIC and YETI tumblers to help you decide which drinkware to buy.

Insulation Technology

RTIC and YETI tumblers are both double-wall vacuum insulated containers. Where they differ, however, is in their lids.

RTIC vs YETI Tumbler Insulation technology
RTIC and YETI tumblers rely on secure lids and double-wall vacuum insulation for maximum ice and heat retention.

Despite the difference in price range, RTIC and YETI Rambler tumblers follow the same construction. Their lineup of tumblers is both made from 18/8 stainless steel. These drinkware feature double-wall vacuum insulation, too. Most insulated or double-wall containers are already effective in keeping drinks cold. Hot beverages, however, don’t stay as hot with this standard approach.

To deliver both ice and heat retention, RTIC and YETI vacuum seal their tumblers as well. This removes all the air between the two layers of the container. Without any molecules for heat to transfer through, the contents inside stay cold or hot for longer.

If you have scalding hot coffee, for instance, you won’t feel the heat while holding the drinkware. It works the same way with cold liquids. RTIC and YETI’s tumblers insulate your cool drinks, preventing the container’s exterior from sweating. This makes the containers particularly convenient for people on the go. You don’t have to worry about getting a cup sleeve or making sure there’s a coaster on your desk.

RTIC and YETI, however, use different lids to keep your drinks locked in. RTIC’s lineup of tumblers comes with a splash-proof lid. The cap also features a flip-top closure that minimizes spills while being straw-friendly, too. YETI, on the other hand, equips its Ramblers with what it calls a MagSlider lid. As its name implies, the lid uses magnets for its closure’s sliding mechanism.

Design and Sizes

You can get RTIC tumblers in 20-, 30-, and 40-oz. sizes. YETI Rambler tumblers, on the other hand, come in 10-, 20-, and 30-oz. capacities.

RTIC vs YETI Tumbler Design and Sizes
RTIC’s design is the same through all its tumbler sizes and is similar to the form of YETI’s 30 oz. tumbler.

RTIC tumblers and YETI Ramblers are available in different capacities. You can get an RTIC tumbler in 20-, 30-, or 40-oz. YETI’s Rambler tumblers, on the other hand, come in 10-, 20-, and 30-oz. sizes.

In terms of design, YETI’s 10 and 20 oz. Ramblers are a cross between frustum and barrel-shaped glasses. Compared to other brands, these tumblers have a wider profile and feel a little more rugged. The brand’s 30 oz. model, on the other hand, features a narrow base that flares on top. It’s practically the same design on RTIC’s tumblers, regardless of size.

The unique profile of YETI’s 30 oz. Rambler and all of RTIC’s tumblers aren’t just for appearances. The narrow base makes for an easier grip, especially for the larger containers. They also ensure the tumblers fit into a cup holder.

Now, standard RTIC and YETI tumblers are stainless-steel throughout. You can, however, get the containers in more creative finishes, typically with a powder-coat exterior. RTIC offers slightly more colors for their drinkware compared to YETI. Nonetheless, the choices will still be size-specific, with larger-capacity tumblers tending to have limited color options.

Performance and Reviews

RTIC and YETI tumblers deliver comparable ice and heat retention. YETI’s Rambler tumblers, however, are sturdier than RTIC’s.

RTIC vs YETI Tumbler Performance and Reviews
YETI has built a reputation for solid and durable drinkware.

RTIC and YETI both claim a modest 5 to 6 hours of heat retention for their tumblers. They also boast up to 24 hours of ice retention. However, it’s also important to consider these numbers are for room temperature situations only. Given this context, reviews on RTIC and YETI tumblers will vary.

Some users claim the budget RTIC containers keep drinks hot for up to 10 to 12 hours, even in below-freezing conditions. Others share that RTIC tumblers will keep your coffee acceptably hot for about 2 hours before being more lukewarm as the day progresses. The same has been said of YETI’s Ramblers. People can expect the premium brand’s tumblers to keep coffee hot for 2 or 2 1/2 hours.

Both RTIC and YETI tumblers appear more consistent with ice retention. Users have mentioned that ice cubes remained in their drinks for a long time, sometimes even the whole day. Suffice to say you won’t be disappointed with either brand for your cool drinks.

Where the more premium YETI has an edge is perhaps in durability. It’s a promise assured by the company’s 5-year limited warranty. Here, you get tumblers with an extra-durable exterior that can take knocks and drops well. The DuraCoat on YETI’s Ramblers is less prone to scrapes and chips, too. Reviews about RTIC’s drinkware, on the other hand, mention the coating on some tumblers tended to chip earlier than expected.


You can upgrade your drinking experience with RTIC and YETI’s tumbler accessories.

RTIC vs YETI Tumbler Accessories
Tumbler handles and straw-compatible lids are just some of the accessories available for these Tumblers.

The standard tumblers from RTIC and YETI are compatible with several accessories. With RTIC, users can get the Tumbler Handle as well as packs of RTIC straws. RTIC’s special handle is made of durable plastic and offers a more comfortable way of griping your drinkware. For the straws, you can choose between stainless steel (which also comes with a cleaning brush) or BPA-free plastic. Both are ideal for sipping tea or juice from your tumblers.

YETI, on the other hand, offers a color pack of its MagSlider, a Tumbler Straw Lid, and its own YETI Rambler Tumbler Handles. Because the lids make use of magnets, the colorful lid replacements are easy to pop on and off. Just like RTIC, the YETI straw lid also makes your tumbler the perfect container for slushies or margaritas. However, the straw lid is only compatible with the Rambler 20 and 30 oz. tumblers.


Although RTIC tumblers are great budget alternatives, the more premium YETI Rambler tumblers tend to be more durable options.

RTIC and YETI both offer stylish and reliable tumblers. They’re definitely great options if you want to reduce waste typically associated with disposable drinkware. These vacuum-insulated containers do a great job of keeping drinks cold and hot. They’re ergonomic and portable, too. If you’re not willing to spend over $20 for a container, however, then opting for RTIC tumblers is a no-brainer. The brand’s direct-to-consumer approach means you can get your hands on their drinkware for less.

If you’re looking for something more premium, it’s hard to miss out on YETI. While affordable brands like RTIC are good alternatives, YETI Ramblers are still the real deal. You can see this most of all in the durable construction of the tumblers. YETI’s so confident with the quality of their drinkware, they’ve even slapped a 5-year warranty on these containers. Yes, they’re more expensive, but the years they’ll last means you will get your money’s worth.
