Boundless VoyageDouble Walled Titanium Cup Insulated Mug Anti-scalding Outdoor Camping Tableware 120ml 180ml 300ml 450ml (4 PCS)

I like how light they are. I bring one when traveling so I always have a clean, non-disposable option in a hotel room. The double wall construction means they don’t sweat when full of ice, or burn your hands or mouth with hot coffee. The light texture makes them non-slip and easy to grip. I wish there were press-in lids I could buy to make them splash-proof.

Made me laugh, because it looks like made for the three bears(Goldilocks), but that is exactly how my family likes their coffee: Cappuccino, flat white, expresso. One for each.

These fit together pretty snugly. No nooks or crannies. Came with 3 mesh bags. Made in china but if its pure titanium it's a good deal. I don't discriminate.

My daughter snitched my set for camping and although I tell myself I am going to be using these for camping, it turns out they are useful enough for trips and excursions to the garage.

Comes with three sizes. The larger size is perfect, but the other two sizes, which fit in larger cup, are too small.

Excellent value for three double-walled titanium stacking mugs. They are good quality, and after a good scrubbing, I am looking forward to using them for a variety of adult beverages around the house and on the trail.

My set comes out to 181.7g. (without storage bags)This is a great set of insulated mugs at an unbeatable price. I use the smallest one for an espresso cup. The other two are large enough for tea and coffee.I have a few other brands of titanium, and the boundless voyage stuff tends to be a more matte/sand-blasted finish. This is not as smooth as something like Keith, and the rough texture does pick up marks easier. You have to run your hand over it to get residue to release when cleaning, unlike something smoother. I do think I prefer something slightly smoother, but it's largely a preference thing. This texture has more grip... just a tradeoff.There are some very very minor blemishes on the lip of the large and smallest cups, but they aren't noticeable unless you're looking at them very closely. Normal wear and tear will make those irrelevant.The shape of the cup edges is very nice, and is very similar to keith, the ninja prepper mug, and snow peak, and the tolerances between cups is quite tight. They do not rattle at all when nested while still allowing each to slide nicely into one another. I also like the shape of the bottom of each cup, which is not entirely flat like a snow-peak or ninja-prepper mug. It has a very shallow round stamped foot to add strength without a weight penalty.This set does come with 3 storage bags, but obviously you cannot use the smaller bags and still nest those cups in the larger one. This is a bit perplexing, and I think just the large one is all that you need. They're nice enough, but could have been omitted for a few more dollars off. These are durable enough not to need a padded bag in your gear.These insulate quite a lot better than the boundless voyage tea maker set that has a pinched-style edge and is much heavier. These feel light and very well insulated given the thickness of each cup. I'm really pleased with this set, and the low cost makes them one of the best deals in titanium. I have been using mine every day, and prefer them over a standard coffee cup. They're just so much more pleasant to use.

I've put coffee and scotch in these, usually separately, and I smell no residue after washing them like I sometimes do with stainless steel or other materials. Serves as a hand warmer on cold nights around a campfire with tea or hot chocolate, but never gets so warm that it burns. A perfectly balanced, decadent luxury.
