Trapper Mug water quantity

475 ml = a tiny bit over 2 cups which is plenty for most freezerbag meals.

Chris thanks for your response

I guess I was assuming a metric cup which is 250 ml. This makes a lot more sense. Can you get the mug to a full boil when it is that full without spillage? Are you using a homemade foil lid of any sort?

I actually don't have the trapper mug. I have a the 550ml cup which came with a lid. You're bound to lose a little if you go to a full boil with a full cup though. I'd probably use a piece of foil for the lid like you mentioned. If you're using treated water anyway then you don't need to get to a rolling boil, it just needs to be hot enough to satisfy you.

Best I can find 1 cup = 236.6 ml in metric.

When I dehydrate food I vacuum seal it with my Foodsaver machine. When I'm traveling SUL with no bowl or cookpot I cut the top off the package and pour about two cups boiling water right into the bag.

Last weekend I took my Trapper Mug with me into the hills to test it alongside the prototype Caldera Cone designed for the Trapper. The quantity of water was just enough to rehydrate my dinner.

It also makes a perfect size for a cup of coffee ; )

Hi Sam,

How'd the Caldera Cone work? I picked one up but haven't had it on the trail yet. (That will change next week.) The mug fits pretty tight and seems like it would be difficult to remove and pour hot water into anything without burnt fingers. I emailed Rand and received prompt replies from both him and George. Rand reccomended leaving the cup in the cone while transferring the liquid which seems like a great idea. What method did you use to transfer the hot water from mug to bag?

I just finished extensive gear testing on the Caldera Cone (the AGG kit) and I am really impressed. I should be posting my review of it in the next few weeks.

I use a Caldera Cone with a 0.9L pot and the cone stays attatched to the pot as I pour. Looks a little odd but causes no problems.

Caldera … I'll never go back!

Laurie: BTW I finally got around to ordering your cookbook yesterday. Don't know what took me so long. Looking forward to expanding my trail menu!

Yes, Ryan the Caldera System as I'm sure Rand, Russ, George, Matt or anyone else affiliated with AGG or TD will tell you (and probably Laurie as well when she finishes her review) works best when left on the pot after cooking. Since the metal on them is lightweight it is easy to maneuver your pot around with the cone still attached. It maintains its ability to act as a sturdy base for the pot and elevates it off the ground helping to minimize convective heat loss too. So, all oddness aside as Michael puts, I don't find it a nuisance at all.

For the record I have a Caldera system for my Snowpeak 900mL, Firelite 550mL and Trapper Mug 475mL – all of which are engineered with extreme precision.
