The Boundless Voyage Titanium Bowl (Ti15163B) is a 400 ml single-wall titanium bowl that goes all-in on saving weight. It weighed 45 g on our scale, and because it’s a single wall, it can also go straight on the stove. I paid $22 for it.
What You’re Getting
A 400 ml bowl made from a single layer of 99.8% pure TA1 titanium, 11.9 cm across and 5.2 cm high, with “Boundless Voyage 400ML Titanium” laser-marked on the side and a curved outer lip that’s comfortable to hold and drink from. Inside there’s a 200 ml measuring mark. It comes in a black mesh sack that lets it dry in your pack, and it’s dishwasher safe. On our scale it weighed 45 g.

On the stove
Being single-walled is what makes this bowl useful beyond eating from. You can put it straight over a camp stove flame or a campfire to boil a small amount of water for a tea or reheat leftovers, which you can’t do with a double-walled bowl. The 200 ml mark inside helps when you’re measuring water for oats or a dehydrated meal.
Hot to hold
The flip side of a single wall is heat. There’s no insulating air gap, so the metal transfers heat instantly: pour in soup or boiling water and the bowl is burning hot to touch straight away. A pot gripper lets you pick it up off the stove, or let it cool a minute before you hold it.
At 400 ml it’s also a small bowl. It’s right for oats, a side portion or a cup of tea, but a big freeze-dried dinner won’t fit. And metal spoons and forks on the sandblasted titanium give an unpleasant scratchy feel and sound, so plastic utensils go better with it.
Cleaning and packing
Food doesn’t stick easily to the smooth titanium, so a little water rinses it clean on the trail. Because it’s thin and single-walled, it takes up very little room and stacks tightly inside a bigger pot. The mesh sack lets it dry while it’s packed. The spork in our photos is the Boundless Voyage titanium spork, and it fits inside the bowl too.
Titanium bowl comparison
We’ve tested several Boundless Voyage titanium bowls. The 500 ml double-walled bowl is the one to hold with hot food in it: the double wall keeps the outside cool. But it can’t go on a flame, and it weighs more than twice as much. The 300 ml bowl with a folding handle also goes on the stove, and its handle lets you lift it off hot, but it holds less.

Conclusion: Boundless Voyage Titanium Bowl (400ml)Conclusion
The Boundless Voyage 400 ml titanium bowl weighed 45 g on our scale, nests tightly in a bigger pot, rinses clean easily and, as a single wall, can go straight on a stove or campfire. It gets burning hot to hold with hot food in it, 400 ml is a small serve, and metal cutlery feels scratchy on it, but for the weight it’s hard to beat. I paid $22.

Yes. I paid $22, and for the weight and the price it's hard to beat. Just keep a pot gripper or a cloth handy for hot food.
