I bought the 800ml version for a thru-hike of the PCT and absolutely loved it. It easily fits my alcohol, stove, fuel, spoon, lighter, and bandana inside. On hikes when I bring a canister stove the standard size isopro canister slips right in. These days I use it every day to drink my coffee and carry it with me in my backpack for use instead of disposable plastic cups. Strange thing is, people LOVE this. Everyone comments on how they think my "mug" is cool. This seems like hyperbole, but I have more people smile at me and say hello when I'm carrying this thing!
I now have the 600ml version for camping and love it just as much. I cannot recommend these cook pots over others on the market enough, and I work for a major outdoor retailer.
