I have yeti rambler mugs, but I like this hydroflask mug for car camping because it's more compact and is the perfect size for cup holders. I'm not sure why Yeti's rambler sizes go from 8oz to 16oz. The hydroflask keeps beverages hot for about 2 hours, which is perfect for me in the mornings when I'm getting ready to drive over to the trailhead and in the evenings when I want hot cocoa. The measurement lines inside the cup are pretty helpful. The only improvement i would like to see would be a better pouring edge/lip. I like to use the hydroflask to measure 1 cup of water, but transferring liquids to another cup or pot results in dribbling onto the edge of the cup.

The 12oz. Outdoor Tumblers are ideal when you don’t need a pint glass. We had some and bought more because everyone liked them for both hot and cold drinks so we needed enough for the whole family.

The tumblers are great, and we may end up buying even more.

The shipping, though did not match the quality of the tumblers. Based on the tracking app, our package Sat in the warehouse for nearly a week before the Carrier picked it up. That was discouraging. In the future, we may just buy from a local store, even if that costs a little more.

Don’t let this shipping complaint dissuade you from getting these tumblers. They are great.

This 12oz outdoor tumbler is small but mighty. I’ve used it many times for hot coffee and it works very well.

The tumbler keeps my drink hot while providing a cool touch on the outside. It fits well in my hand while also providing a comfortable, non-slip grip.

What I like about this tumbler is how nicely it fits in a cup holder, especially in my car. I have other tumblers that are designed to be different or to look cool, but they don’t fit cleanly in a cup holder. This tumbler does, which is very convenient.

The cover fits very snug. Removing it takes a bit of muscle, but I’m fine with that since it provides a tight seal. I can feel confident that it won’t leak or drip.

One recommendation I have for the lid would be to have an option to close the lid. There were a few occasions while driving or even walking around that coffee managed to slash out. It does drain back into the tumbler but it would be nice to have the option to seal the opening to avoid any slashing or leaking if it’s tipped over.

Quality-wise, this is a solid and well made tumbler. It’s sturdy and will keep your drinks hot or cold. It also looks sleek and fits well as part of the larger outdoor collection. If there would be the option to seal the opening, this would be the perfect tumbler.

This 12 ounce tumbler is perfect for everyday use. It can be used for anything cold, from water, iced tea, protein shakes, etc. It can also be used for anything hot, from coffee, tea, hot cocoa, etc. It keeps my drinks cold and hot for hours! While also keeping them fresh and preventing anything from getting in it. The lid features honeycomb insulation to help with temperature control. So my hands don't get hot or cold when holding this. It's also splash resistant which works fairly well! However, if it's shook to hard or tilted a certain way it will spill out some. Another thing, if you overfill this it will come out all over you. I have a bad habit of overfilling my cups, this has helped me to not do that. As long as you don't get it over full it won't come out all over you. It has two lines marked in the cup, one is 1/2 cup, the other is 1 cup. I definitely like having the lines showing that for easy measuring. Another plus is this is stackable, so it can be stacked with other tumblers for easy carrying and storing. I also want to mention this is stainless steel and very heavy duty. This will last through just about anything! You don't have to worry about it dropping and breaking or the lid popping off. If you own a dishwasher, this is also dishwasher safe. I have used so many different tumblers, none compare to this. This has now become my all time favorite. I will most definitely be getting more of these tumblers. With me working in construction these are perfect with them being heavy duty. If you're looking for a great tumbler that's easy and convenient for on the go this is it!! Even if you're not on the go, this is even great for everyday use at home as well.
