The Boundless Voyage Titanium Mug (Ti3051D) is a 250 ml titanium mug with folding handles and a lid. It weighs 70 g with the lid, and it’s the mug I grab for a camp coffee, and more and more at home too. I paid $26 for it.
What’s in the box
A 250 ml mug made from 99.8% titanium, with a matte grey finish and the Boundless Voyage logo laser-etched on the side. Two handles fold flat against the body when you pack it, and the lid sits snugly, with a small loop to lift it off without burning your fingers. It comes in a mesh storage bag and weighs 70 g with the lid.

Coffee at camp
There’s nothing to set up: unfold the handles, pour your drink and go. I’ve used it for morning coffees and herbal teas before bed, including with the Boundless Voyage titanium coffee filter sitting on top. For something stronger, pair it with our portable electric espresso machine. 250 ml is right for a standard coffee or tea without being bulky, and it cleans with just a rinse, with no lingering smells or stains.
The lid keeps a drink warm a little longer and keeps bugs and ash out when the wind picks up. It’s not watertight, though, so it’s for sipping, not for carrying a full mug around.
On the stove and the fire
It’s single-walled, so you can boil water in it straight over a gas stove, a wood stove or coals. I’ve used it on both with no warping or damage. Take the lid off and keep the flame low when you boil in it. The titanium heats fast, so the body gets hot, but the fold-out handles stay comfortable to hold.
Built to last
After several trips, from the Blue Mountains to the inland tracks around Capertee, it has been dropped on rocks and stashed in bins next to pots and pans, and it hasn’t dented or discoloured. The handles haven’t loosened, the welds are clean and the titanium never picks up flavour from past brews. The tapered shape also stacks neatly for packing.
Titanium mug comparison
We’ve tested several titanium mugs and cups. The 420 ml Boundless Voyage mug and the 450 ml cup with lid hold almost twice as much and work as a small pot for a meal, and the Ti Artisan nestable cup comes in four sizes that stack. For a single coffee, the 250 ml is the lightest. Our titanium cookware guide compares them all.

Conclusion: Boundless Voyage Titanium Mug (250 ml)Conclusion
The Boundless Voyage 250 ml titanium mug weighs 70 g with its lid, goes over a stove or the fire, and has taken knocks on several trips without a dent. The handles fold flat, the lid keeps bugs and ash out, and it never takes on a taste. It isn’t insulated and 250 ml is one coffee, but for a light, tough coffee mug it’s hard to beat. I paid $26.
