Know before you buy
Yes, the Rambler 30-ounce is specifically designed with a tapered base to fit most standard vehicle cup holders, despite its large capacity.
The MagSlider lid is designed to prevent splashes and keep your drink at the right temperature, but it is not leak-proof. You should avoid tossing it into a bag while full, as it is not intended to be airtight.
Yes, the entire tumbler, including the lid, is dishwasher safe. You can place it on either rack without worrying about damaging the stainless steel or the finish.
No, the DuraCoat finish provides a textured, non-slip grip. Additionally, the double-wall vacuum insulation ensures the exterior remains sweat-proof, so you won't deal with condensation or slippery surfaces.
Yes, the tumbler is constructed from 18/8 food-grade stainless steel, which is highly resistant to rust and does not retain flavors or odors from previous drinks.
While performance varies based on ambient temperature and how often you open the lid, the double-wall vacuum insulation is engineered to keep beverages hot for several hours. For best results, pre-heating the tumbler with hot water before pouring your coffee can help extend heat retention.
