  • Fantastic Quality, Perfect for On-the-Go Hydration!
Color: Canopy Green
I recently bought the YETI Rambler 18 oz Bottle, Vacuum Insulated, Stainless Steel with Chug Cap, and I have to say, it's quickly become my go-to bottle for staying hydrated throughout the day. The quality is outstanding, and it truly lives up to the YETI reputation. First off, the build of this bottle is exceptional. The stainless steel construction feels incredibly sturdy and durable, and the vacuum insulation works wonders at keeping my drinks cold for hours. Even on the hottest days, my water stays refreshingly chilled. The Chug Cap is a great addition, making it easy to take quick, satisfying sips without any spills. The 18 oz size is perfect for carrying around—whether I'm heading to the gym, going for a hike, or just running errands. It fits comfortably in my bag and is just the right size to hold enough water without being too bulky. However, I do wish I had opted for a larger size. While the 18 oz is convenient, I find myself refilling it more often than I'd like, especially on longer outings. Cleaning the YETI Rambler is a breeze, too. The wide mouth makes it easy to scrub the inside, and all the parts are dishwasher safe, which is a huge plus for convenience. The bottle also doesn't retain any flavors, so I can switch from water to flavored drinks without any lingering taste. Overall, the YETI Rambler 18 oz Bottle with Chug Cap is a fantastic investment for anyone in need of a reliable and high-quality water bottle. Its durability, excellent insulation, and user-friendly design make it a standout choice. While I love my 18 oz Rambler, I definitely wish I had gone for a bigger one to cut down on refills. Nonetheless, I'm extremely satisfied with this purchase and highly recommend it to anyone looking for a top-notch water bottle. ... show more

  • Such a great little thing
Color: Big Sky Blue
I bought this one because the one the next size up was bigger than what I was looking for. The size fits right in my hand. It fits in the side pocket of my backpack. It keeps things cold as usual. I stopped keeping track at 48 hours. There might not have been ice in there, but it was still cold. I’m a true believer in yeti. Whatever comes along or whatever has been, will never be as good as them if they keep up with the quality and design they have thus far. I work in healthcare so the size shape color and design makes my cup stand out from all the other obnoxious drinks at the nurses station. I’ll take a picture of it next to the rambler I felt was too big. I just wanted something to hold my hand and have never seen one in person. The unique drinking spout, which is inside let me enjoy my favorite drink drinks with my favorite drink add-on, which is crunchy ice that you can find at Sonic, Zaxbys, Gate (if you know you know). For some reason, the perfect ratio of liquid to ice comes out of this little spout, making this rambler my most cherished accessory thus far and I own a lot of accessories. The only downfall is that it is hard to open for me sometimes. This has happened with other types of cups. I broke my hand twice and I’m getting old so maybe the youngsters could do better. Yeti is always expensive but you really only need one or two of their products to be thoroughly happy. It’s worth the price. ... show more

  • A great item from Yeti
Color: Cosmic Lilac
This item is just the quality that is expected from Yeti. It keeps coffee hot for several hours. If drinking something cold, it keeps it cold for hours. It is a convenient size to carry in a backpack or computer case. It is functional, pretty, easy to use, and of great value for the money. The color is attractive too. ... show more

  • Fits refrigerator door dispenser perfectly.
Color: Ultramarine Violet
Wide mouth makes ice dispensing nice. Not chasing ice cubes on kitchen floor. Ice lasts a long time. Also got the straw flip cap.

  • The Water Bottle That Finally Got Me to Hydrate
Color: Rescue Red
I’ve never been great at drinking enough water. I needed something easy to carry, and the YETI Rambler has been perfect! It keeps my drinks ice-cold all day, fits comfortably in my bag, and the Chug Cap makes sipping effortless on the go. It’s a tad pricey, but the quality makes it totally worth it.

  • Survived My 9-Year-Old — Enough Said.
Color: Firefly Yellow
My son drags this Yeti Rambler everywhere — the park, the car, the backyard, even the bathroom (don't ask). It's been dropped, kicked, and launched off the couch, and it still looks brand new. Keeps water cold for hours and somehow keeps him entertained. Worth every penny just for the durability alone. ... show more

  • Yeti Importance of Value for Money
Color: Rescue Red
I love my yeti items. This one is a vibrant red and is more light weight than some and came with the chug lid. I really like it better than the straws and it makes it COMPLETELY spill proof. The price is well worth the quality.

  • I like it.
Color: Cosmic Lilac
This is my first Yeti, and I am generally pleased with it. However, I had higher expectations regarding its ability to maintain the coldness of my water. When I add approximately four ice cubes and leave the bottle in a warm environment for an extended period, the ice melts within four to five hours, potentially less depending on the ambient temperature. Conversely, when used indoors with only ice, the ice remains intact for approximately seven hours, and the water stays cold for several more hours. Fortunately, I have not experienced any leakage issues that some users have reported, and I hope this remains the case. The packaging of the water bottle was inadequate, as it could have easily been damaged if dropped. Fortunately, the delivery person handled my package with care, and there was no damage. I appreciate the color and texture of the bottle and would consider purchasing a different style of Yeti in the future. However, I wish it could maintain colder temperatures for a longer duration. ... show more
