This is the mug made for marathon hydration. The Rambler® 42 oz Mug with Straw Lid is built for those who need serious refreshment — whether you’re road-tripping, RV-ing, or just committing to a full day of sipping ice-cold lemonade by the lake. With its reusable straw, sturdy lid, and double-wall vacuum insulation, this mighty mug keeps your drink cold all day and your conscience clean (because single-use straws are so last season).
Please note: The Straw Lid is not for use with hot beverages.
Built for All-Day Iced Sips
18/8 Stainless Steel
Kitchen-grade stainless steel that resists rust, dings, and punctures.
Double-Wall Vacuum Insulation
Keeps your beverage cold — no matter how long the trip or how hot the day.
Dishwasher Safe
Because hydration heroes shouldn’t have to scrub.
Reusable Straw + Lid
Shatter-resistant, BPA-free, and equipped with a molded stopper to keep your straw right where it belongs.
Elongated Handle
Big mug, easy grip — even when you’re juggling kids, keys, and camp chairs.
Will It Fit in My Cupholder?
Yes. It’s cupholder-compatible — just check yours is at least 3" wide for a comfy fit.
Can I Use It for Hot and Cold Drinks?
For cold drinks only with the Straw Lid. If you’re going hot, swap it for a MagSlider™ Lid (sold separately).
Is It Dishwasher Safe?
Absolutely. Mug, lid, and straw — all safe to toss on the top rack.
How’s It Different from the Travel Mug?
This mug is threadless and works with press-fit lids like the Straw and MagSlider™. Travel Mugs use a threaded Stronghold™ Lid only.
Can I Swap the Lid?
Yep! The MagSlider™ Lid is compatible if you’re switching to something hot. Just make sure you get the right size.
Is It BPA Free?
Yes. All YETI® Drinkware is BPA free.
Is There a Warranty?
You bet — it comes with a five-year warranty.
