Rambler® 20 oz & 30 oz Travel Mugs FAQ

Which lid fits my Rambler® Travel Mug?

The Rambler® Travel Mug comes with our new twist-on, leak-resistant, double-magnet Stronghold™ Lid. This is a special design that’s only available in the Travel Mug family, so be sure to check which size you need. The Rambler® 20 oz. Travel Mug uses the 20 oz. Stronghold™ Lid, while the Rambler® 30 oz. Travel Mug uses the 30 oz. Stronghold™ Lid.


What’s the difference between the MagSlider™ Lid and the Stronghold™ Lid?

The original MagSlider™ Lid is splash resistant, comes in three sizes, has a single-sliding magnet, and presses on. As for the Stronghold™ Lid, it’s leak resistant, special-made for the Rambler® Travel Mug, and comes in two sizes. Both the 20 oz. and 30 oz. Stronghold™ Lids are backed with double-magnet technology and twist on for an extra-tight fit. These Stronghold™ Lids can also be positioned for both left- and right-handed users.


Is the Stronghold™ Lid leakproof?

The Stronghold™ Lid is leak resistant (when closed) thanks to its dual-slider magnet technology that adds a strong layer between your free-flowing drink and the outside world. That said, don’t even think about throwing this mug inside your bag. If leakproof drinkware is what you’re after, check out our lineup of Rambler® Bottles and leakproof bottle cap accessories including the HotShot™ Cap, MagDock™ Cap, and Cup Cap.


Does the Rambler® Travel Mug feature the same size handle as my Rambler® Mug?

The Rambler® 20 oz. Travel Mug shares the same handle size as our 10 oz. and 14 oz. Rambler® Mugs. But, the Rambler® 30 oz. Travel Mug has its own size which is slightly larger than other Rambler® Mugs.


I want to add a Straw Lid or MagSlider™ Lid to my Rambler® Travel Mug. How can I do that?

The Rambler® 20 oz. and 30 oz. Travel Mugs only fit the Stronghold™ Lid they come with. The good news is that it’s the most leak-resistant lid we offer. But if a Straw Lid is what you’re after, our Rambler® 26 oz. Cup comes with one, just like the MagSlider™ Lid comes with our Rambler® 20 oz. and 30 oz. Tumblers.


Which colors are available for the Rambler® Travel Mugs?

Black, Navy, Seafoam, and a handful of seasonal colors. Check back for new color offerings.


Can I put a Chug Cap on the Rambler® Travel Mug?

The Chug Cap is only compatible with Rambler® Bottles..


Does the Stronghold™ Lid fit my other Rambler® Drinkware?

These are special-made for the Rambler® 20 oz. and 30 oz. Travel Mugs and won’t fit with other Rambler® Drinkware.

Does my Rambler® Travel Mug fit in a cupholder?

Sure does. Both sizes are compatible with most cupholders. The Rambler® 20 oz. narrowest diameter is 2.75” and the height from the bottom of the mug to the base of the handle is 3.75”. The Rambler® 30 oz. narrowest diameter is 2.73” and the height from the bottom of the mug to the base of the handle is 4.36”. Basically, if your cupholder isn’t unusually big, small, wide, or strangely shaped, it should fit just fine.


Can I get my Rambler® Travel Mug customized?

Absolutely. Front and back customization is available for both sizes.


Which design galleries are available to customize my Rambler® Travel Mug?

Most of our stainless steel and DuraCoat™ drinkware can be customized, however certain products may be excluded due to product availability, limited marking areas, or difficulties in marking due to the design of the product. Any product that is customizable will have our customizer option available during checkout.


Are the Rambler® Travel Mugs replacing the Rambler® Tumblers?

No need to say farewell — both the Rambler® 20 oz. Tumbler and Rambler® 30 oz. Tumbler are here to stay. Just consider these the newest addition to our Rambler® Drinkware Family.


Will you be making other colors available for the Rambler® Travel Mug Family?

Keep your eyes peeled. We always have new colors on our mind.


Can I trade in my Rambler® Tumbler for the same size Rambler® Travel Mug?

No swapping, but we like having both on our shelves.


Can I put carbonated beverages in my Rambler® Travel Mug?

No, these products are not for use with carbonated beverages and should not be used as storage for food and perishables.


Recall FAQs

Is this lid the same as the recalled lid?

This is not the lid that was recalled in October 2020.


What is different about this product compared to the original Rambler® 20 oz. Travel Mug that was recalled?

Several updates have been made to ensure mug contents are not expelled when the mug is filled with hot liquids and agitated or inverted. Key functional updates include reducing the vapor path and pressure through the bottom slider, releasing when sliding the upper magnet into the open position. Improved user experience updates also include top slider grip points on both directions as well as a drinking channel for better flow of contents.


Is this product safe to use?

Yes, this product is safe to use. Please be sure to follow caution statements. Hot contents can cause pressure to build within the vessel resulting in a release of hot steam. Open with care when using hot beverages to avoid burns. This product is not for use with carbonated beverages and should not be used as storage for food and perishables.
