Rambler® 20 oz & 30 oz Travel Mugs FAQ

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.

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.

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.

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.

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.

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

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

The entire travel mug (lid included) is dishwasher safe, but you can always hand wash it with hot and soapy water, too — just be sure to dry it well. For full cleaning instructions, click here.

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.

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

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.

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.

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

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