The Boundless Voyage Titanium Bowl with Folding Handle (Ti15156A) is a 300 ml single-wall titanium bowl that borrows from the classic Sierra cup: a folding handle, a pouring spout and measuring marks. It weighed 45 g on our scale, and it works as a bowl, a tiny saucepan and a measuring cup. I paid $24 for it.
What You’re Getting
A 300 ml bowl made from a single layer of 99.8% pure TA1 titanium, 12 cm across and 4.5 cm high, with “Boundless Voyage 300ML Titanium” laser-marked on the side. A wire handle folds out to 19.5 cm long and snaps flat along the curved edge when you’re done, and the rim has an anti-drip pouring spout. Inside there are 100 and 200 ml marks. It comes in a black mesh bag with a red drawcord, it’s dishwasher safe and it weighed 45 g on our scale.

A bowl and a mini pot
The folding handle and the spout are what set this bowl apart. Because it’s a single wall, you can put it straight over a camp stove, a wood stove or an open fire to boil water, brew a tea or warm a small snack, then use the handle to lift it off and the spout to pour without dribbling. The 100 and 200 ml marks inside make it a handy measuring cup too, for water for oats or a dehydrated meal.
The handle stays mostly cool, so you can move or hold the bowl while it’s hot without burning your fingers. The rim is another matter: with hot liquid inside it heats up instantly, so sipping straight from the edge is uncomfortable until it cools down a bit. There’s no lid either, so water takes longer to boil and ash or leaves can fall in over a campfire.
Small, light and easy to packSmall, light and easy to…
At 300 ml it’s the smallest bowl we’ve tested: right for a side dish, a tea or a coffee, or measuring ingredients, but not a full meal. The upside is the size in the pack. The handle swings out of the way and folds flat, and at 4.5 cm high it nests easily inside bigger cookware. The spork in our photos is the Boundless Voyage titanium spork, which fits inside it for packing.
300 ml or 450 ml?
Boundless Voyage also makes this bowl in a 450 ml version, with the same folding handle and pouring spout. It’s 13 cm across and 5 cm high and weighs 53 g, so it’s only a little bigger and heavier but holds half as much again: enough for a small meal rather than just a tea or a side. We have both: I paid $25 for the 450 ml.

Titanium bowl comparison
We’ve tested several Boundless Voyage titanium bowls. The 400 ml bowl is also single-walled and goes on the stove, with a little more room, but has no handle, so it’s too hot to hold with hot food in it. The 500 ml double-walled bowl stays cool to hold but can’t go on a flame.

Conclusion: Boundless Voyage Titanium Bowl with Folding Handle (300ml)Conclusion
The Boundless Voyage 300 ml titanium bowl is a bowl, a tiny saucepan and a measuring cup in one: a single titanium wall that goes on a stove or fire, a folding handle that stays mostly cool and a spout for neat pouring. It weighed 45 g on our scale and packs flat. The rim gets hot with hot drinks, 300 ml is small and there’s no lid, but it’s the most useful bowl of the bunch. I paid $24.

Yes. I paid $24 for a bowl that's also a mini pot and a measuring cup, and at 45 g it's an easy one to take.
