  • Perfect for me
Style: 25oz Color: Big Sky Blue
This is my first Yeti. I love love it. Adore the color. 25 oz perfect size for water, fits cup holders, it’s not too heavy, keeps water very cold, the handle is just right or you can hold tumbler with your hand comfortably . First time having tumbler with straw. It’s great and fun to drink from. Comes with a durable straw Easy to clean with a brush for wide straws. The whole tumbler is very easy to clean so I don’t have to worry about mold build up. I’ve had many water bottles but this is a real winner for everyday use at home or in the car. The other thing I like is I can purchase another lid if I don’t want to use a straw. Very pretty excellent quality. . ... show more

  • Super sturdy stainless steel walls, huge capacity
Style: 42oz Color: Big Wave Blue
GINORMOUS and oh so sturdy - this will outlast my teenager and gorilla husband! Cold drinks only - at 42 ounces, I guess that would be excessive caffeine - nice thicker straw perfect for sports drink mixes. Easy to clean and it actually fits in my Toyota cup holders - both Corolla and RAV4. I bought this on Prime Day and got a screaming good deal. As for leaks, the straw hole is understandably a potential leak point, but at this size, if wedged into that cupholder, it'll be just fine. ... show more

  • Great mug!
Style: 35oz Color: Papaya
I recently purchased this insulated container, and I'm incredibly impressed with its performance. The product effectively maintained a low temperature, exceeding my expectations. After a full day, and even into the next, I was surprised to find ice still present. This remarkable feature highlights the quality of the design and materials. I particularly Loved appreciated their addition of the handle feature on this model, and this review is coming from someone who's been a Yeti enthusiast for many years. Overall, I would highly recommend this product for anyone seeking exceptional insulation capabilities! ... show more

  • Best Product for Temperature Regulation
Style: 42oz Color: Key Lime
We have bought all size Yetis and will not buy any other brand. They have all have delivered the same quality, functionality and durability. Their value is beyond compare: they maintain the appropriate temperature for very long periods (even in the heat of the deep south) better than any other brand we have tried;; are extremely durable (we take them everywhere and they have been dropped, scraped and bumped with no damage); and the stainless steel composition is strong, easy to clean and dishwasher safe. Should you ever need them, Yeti makes replacement parts (straws, rubber gaskets and lids). Yeti makes the best products we have ever purchased. Due to our experience, we are about to invest in a large Yeti ice chest. You can’t go wrong with the brand. ... show more

  • Beautiful Tumbler
Style: 42oz Color: Big Wave Blue
I like this mug. Keeps coffee cold/warm for a long time. Beautiful color, great quality. It also comes with a good quality straw. I am obsessed.

  • YETI Rambler 35 oz Straw Mug is a fantastic choice for a reliable, high-capacity tumbler
Style: 35oz Color: Big Sky Blue
I recently purchased the YETI Rambler 35 oz Straw Mug in Big Sky Blue, and it’s quickly become my go-to for staying hydrated on the go. Here’s my take on this hefty hydrator. The double-wall vacuum insulation lives up to YETI’s reputation. I filled it with ice water in the morning, and even after hours in a hot car, the ice was still intact, and the water stayed refreshingly cold. Perfect for long road trips or beach days. Made from 18/8 stainless steel, this mug feels indestructible. It’s puncture- and rust-resistant, and I’m confident it could survive a drop or two. The elevated handle makes it easy to carry, especially for those with arthritis or smaller hands, and it fits perfectly in my car’s cupholder. The straw lid is a game-changer for sipping iced coffee or water without spilling, and the molded-in stopper keeps the straw secure. Both the mug and lid are dishwasher-safe, which is a huge plus for daily use. No fuss, no hassle.The Big Sky Blue is vibrant and eye-catching. It’s a beautiful shade that stands out without being too flashy. Like most YETI products, this mug isn’t cheap. While the quality justifies the cost for me, it might be a stretch for budget-conscious buyers. However, The YETI Rambler 35 oz Straw Mug is a fantastic choice for anyone who needs a reliable, high-capacity tumbler for cold drinks. Its insulation is top-notch, the design is practical, and the Big Sky Blue color adds a fun pop. Just be prepared to invest in an extra lid if you want versatility for hot beverages. I’d recommend this to anyone looking for a durable, stylish way to stay hydrated all day! ... show more

  • Great Color and Quality!
Style: 42oz Color: Ultramarine Violet
Love my YETI. I purchased an insulated mug from Walmart a year ago, and the handle broke. I should have just bought the YETI to begin with. You get what you pay for. Functions as advertised. Ice remains in the cup for 18 hours or more. I love the straw, too. It's hard plastic and easy to clean with or without a straw cleaner. ... show more

  • Good overall but straw could be better
Style: 25oz Color: Tropical Pink
I love my yeti but the straw isn't super long lasting. No matter how much I clean it it still has a noticable line where it meets the lid. It also has a bit of a dent in the bottom of the cup, potentially from the straw I'm not sure. Everything else about the cup is great- keeps my drinks cold like a yeti should. I think the insulation could be a bit better if the straw hole had a silicone liner or something. The lid won't leak as long as it doesn't splash out of the straw hole. I like the size too- not too big or small. It's comfortable to hold and carry, but I wish the handle was more rounded. It's fairly easy to clean with a straw and bottle brush, but you want to make sure you take off the silicone ring around the lid so moisture doesn't get trapped in it to prevent mold. ... show more
