Works Well

  • Familiarity:I've put it through the wringer

This is one of the better backpacking mugs I've used. It's lightweight and holds a large volume. Its short, wide shape has great stability- very important in my opinion. The insulation is just enough as it protects your hands but allows some heat to escape so you can begin to drink your coffee sooner rather than later.



Yes the lid can be tough to take off. I often have to stick the handle of my spoon in the mouth opening and pry it out. Oh well, it's easier than growing up.

It's..... fine

    For the price I guess it's okay. It definitely does a good job at containing the liquid, it's fine for any liquid hot or cold. The top (at least on mine) is very hard to take off, taking it off with a hot beverage in it would be asking for burns! The cup itself is not insulated so your beverage loses temperature fast. It has the sleeve with it but all the sleeve does is keep your hand safe. The sleeve after using it a few times becomes loose and slides off easy. Overall I think there are better options out there but if your looking for something cheap that does the job this works fine.

    Does the mug have measurement markings on...

    Does the mug have measurement markings on the inside? Useful when making soup. Thanks in advance for an answer.

    No problem. That's not quite soap making, but I know what you're talking about. With any cup or mug that has no marks, I always prepare the ideal batch at home with a precisely measured amount of water, then lightly scribe a small line on the inside at the increments I need for the food and volumes I usually use. As you use a cup more, you also start to get a sense of what amounts look like.

    YOu can separate the sleeve and the mug...

    YOu can separate the sleeve and the mug right? Is there any room to drill two small holes in the insulating sleeve in order to run some line thru it to create a hanging loop of some kind?
