I've used a carabiner with mine....attach it to either my belt or a pack if I'm using one. Then, I can use it in the morning, rinse it out, hang it off my belt, and reuse it at lunch rather than toss that refill out.
That's exactly what I do, except it's attached to my purse. On occasion, I'll have a purse that has a removable strap, so I'll hook it onto that. We don't do breakfast - maybe a quick pastry as a grab-and-go - and I can't drink my coffee that fast. So I just take it with me. I find having it makes it easier for me to stay hydrated, since I won't carry around a bottled water with me - too heavy, and I hate the plastic waste. I also won't spend the money on bottled water. If I do buy a drink, I'll rinse out my mug and put the drink in it. I find it more pleasant to drink from the mug than a paper cup. (This is especially true at AK, where straws are not permitted.)

or how hot it is and he drinks several cups a day.




I guess the machines were breaking down too much. how sad.
