Rambler 20 oz Stackable Tumbler, Stainless Steel, Vacuum Insulated with MagSlider Lid

I absolutely love my Yeti Rambler 20 oz Tumbler! It holds just the right amount of liquid—not too big, not too small—making it perfect for daily use. Whether I’m heading to work, running errands, or just relaxing at home, it’s super portable and fits easily in my bag or car cup holder. The bright, vibrant colors are a fun touch and make it easy to spot. Plus, it keeps my drinks hot or cold for hours, which is a huge win. Definitely one of my favorite purchases—highly recommend!

Nice cup that is easy to use and clean. Keeps my cold drinks nice and cold for hours on end and my ice melts slowly. Durable and a beautiful color. Good quality.

Exceeded expectations. Keep hot liquid hot and cold liquid cod for long periods of time. Exact color as on picture. Not to heavy, very durable. Easy to grip and hold. Does not leak easily. Designed perfectly for all cup holders.

We are absolutely happy with this thermal cup! It keeps drinks hot for a really long time, which was a pleasant surprise. The design looks modern, stylish, and very high quality. What impressed us the most is how durable it is — even after a few accidental drops, it still looks perfect, with no dents or damage at all. You can really feel that it’s made to last. Great quality, great performance, and beautiful appearance. We’re very happy with this purchase and would definitely recommend it!

This tumbler is the real deal. Keeps my coffee hot for hours and my cold drinks stay ice cold all day long. Not even exaggerating - I've left ice in there overnight and it's still there in the morning. The MagSlider lid is super handy and doesn't leak when I toss it in my bag. Love that it's stackable too so it doesn't take up a ton of space in my cabinet. Yeah it costs more than other tumblers but you can tell the quality is there. Thing is built like a tank. Already want to grab another one.

Great quality. The lid closes easy with magnetic pull. It is not a complete seal meaning it will leak a bit if you shake it but it is great quality and color. I’m very satisfied with it.

I prefer my 16oz Contigo autoseal travel mug for daily use, but when I want to use a straw, the Yeti tumbler with MagSlider works better. They're both pretty good at keeping drinks hot or cold. The Contigo is better for spills. The Yeti obviously has to have the slider closed, but even then, it'll leak some if it tips, especially if it rolls or gets rattled once tipped. I like the Yeti Tumbler, especially the stackable design, but it's false advertising. The 20oz stackable tumbler only holds 16oz. The 30oz version is ridiculously big and only holds 26oz. The 20oz fits fine in a car cup holder, but sinks down lower than you'd expect, especially if you're used to standard 22oz paper cups. It would be nicer if it were a little taller to actually hold 20oz of liquid.

This is the perfect size and fits in my cup holder easily. The color is adorable and looks even better in person. It keeps my coffee hot for a really long time, which I love, and it feels super durable. Exactly what I expect from YETI and worth every penny.

Only had the flask for a month and the plastic on the lid is already cracking. It’s also not leak proof! Even in a secure cupholder in a car on bumpy roads it’s still going to leak a bit. However because of the magnetic design of the lid and closure it’s easy to clean and does keep liquids hot for a while… but still, not sure it’s worth the money.

Excellent quality

Excellent so far, only coffee and tea.

Muy bonito color. Tarda en llegar porque viene del extranjero. Pero si esta muy padre

The YETI Rambler 20 oz Stackable Tumbler has become my go-to for keeping drinks hot or cold during long photography sessions. Its vacuum insulation is outstanding, keeping my coffee hot for hours during early morning shoots and my water ice-cold on hot days. I’ve tested it out on various outings, and the temperature retention is impressive, even in extreme weather. The MagSlider lid is one of my favorite features. It’s easy to slide open and closed with one hand, which is super convenient when I’m juggling camera gear. The magnet also helps prevent spills, although it’s not entirely leakproof if tipped over. The lid is also clear, which allows me to quickly see how much of my drink is left. The stackable design makes storage convenient, especially when packing multiple tumblers for a trip. The stainless steel construction is durable, standing up to bumps and drops without denting or scratching, which is essential when I’m on rugged photography adventures. Another thing I appreciate is how comfortable it is to hold, thanks to its no-sweat design—no condensation on the outside, even with ice-cold drinks. The size is perfect for fitting in my car’s cup holder, making it easy to take with me on the road. Overall, the YETI Rambler 20 oz Tumbler is a durable, versatile, and reliable travel companion for anyone who needs to keep drinks at the perfect temperature. Highly recommended for photographers, travelers, or anyone on the go!
