Nesting mugs & caldera cone?

I suggest the a Caldera Cone with a Snow Peak Mini Solo kit.  I had the original version, and I think the updated one is probably better.  It’s a two piece cone.  The one-piece Sidewinder is lighter, but then you are talking a wider pot, and it will really only fit a folding mug for the 2nd person – it doesn’t sound like what you are asking for.  Evernew has a 750/400 ml stacking set as well that might be lighter than the Snow Peak.  These two  might work well for you because the second mug is nested outside the larger pot, and both are mug sized.  The cones are typically sized to fit the pot, and nesting another mug inside with a cone might not work – others can correct me if I’m wrong.  I never used the Ti-Tri inferno option for woodburning, but experimented with twigs without that option and it was OK for me.  The Kojin alcohol stove and esbit both work better in my mind.

If you want to pack the cone completely inside the mug, two identical mugs packed opening to opening with the cone inside might make more sense than nesting mugs.

The idea is to boil water in one mug, then split into the second mug so that two of us can have coffee/soup etc.

This is what we do but instead of a second Ti mug, we use a cut-down PP ice cream pot; it’s much lighter than a second Ti mug.

Two thoughts, neither might be helpful:

1) MLD shows their 520 mug as fitting a Talenti container inside. Talenti containers will deform but Whole Food gelato containers are polypropylene (?) and do not melt. I have both containers here and can dimension with calipers if you want to confirm sizes. You’d likely want a cozy on the gelato container (some relectix?) because the plastic gets really hot. https://youtu.be/Y71kbhlIlXs

2) email Trail Designs. They are very helpful and will likely guide you well.

just curious, you are boiling water for two in a mug for one. Is it your expectation that the bigger mug hold approximately double what the other mug can hold, or are you just planning to have each mug at half capacity? If it was me, I’d see if I could nest a Toaks 700UL pot (115mm diameter, 2.3oz without lid) inside a Toaks 900 (130mm diameter, 3.7oz with lid) and then see if I could get a Sidewinder Ti-Tri system made that will fit the 900 diameter, but nest inside the 700. This should be doable, even though the 900 is slightly shorter than the 700. This would allow you to boil water for approximately 2x 12oz drinks. Idk if that is what you are trying to do, though.

Thanks everyone, your suggestions really helped me narrow down what I want.

We’re planning to do a lot more hiking and bikepacking this year. I have a couple of Trangias and we’ll take one of those for lazy trips where we want to cook nice meals, but on most of the others we’ll have to carry all our water so we’re minimising weight elsewhere. On these trips we’ll rely on cold food but with a little hot coffee or soup for comfort.

If we were going to get really technical about quantities, I’d say boiling 250ml (8oz) is enough – splitting this into two cups, adding some cold water / milk to each, would give us a reasonable hot drink each. Bigger is fine, but we don’t need pasta pots.

My main desire is to get a cone based setup (convenience, wind protection, efficiency, stability). We’ll carry some alcohol but use wood where we can. Often we’ll be able to just have a camp fire, and having a pair of ti pots rather than one plastic one gives us some flexibility.

The Snow Peak and Evernew options suggested seem fine – I had imagined a pair of mugs of similar proportions, but there’s no reason they have to be. It does look like the trick is to find a pot and cone combination and then add the second pot to the OUTSIDE, rather than the inside where it may not accept the packed cone.

I also found a handy reddit post explaining the difference between the different systems. I’ll repost it here because I thought it was so useful:

Classic: does not fit in your pot. Stored in a plastic caddy that doubles as a pair of coffee cups. Fits a wide variety of pots.
Sidewinder: fits in your pot because it’s short and your pot is wide. Mostly compatible with shorter/wider pots.
Fusion: fits in your pot because it splits in two pieces. Mostly compatible with taller/skinnier pots. Leaves more of the pot exposed to the wind than the Fissure. Also fits slightly different pots than the Fissure.
Fissure: fits in your pot because it splits in two pieces. Mostly compatible with taller/skinnier pots. Extends further up the sides of the pot than the Fusion. Also fits slightly different pots than the Fusion.

Anyway, I’m leaning towards one of the existing two-pot kits suggested, but I’ll also look into whether I can put together something a bit smaller.

Thanks again!
