Boundless Voyage Camping Titanium Cup 350ml/11oz Coffee Mug Ti3022D

This titanium cup works well, however it’s interesting. Because there is a sealing ring of silicone, and no air outlet on the lid, it closes pretty securely which makes it pretty leak resistant. However, if you put hot liquids and snap on the lid, it’s going to create a vacuum and make it really hard to open it back up. So I don’t recommend covering the lid all the way after pouring a hot drink. Besides that, the cup is fine. It’s insulating, but not entirely as the cup still gets warm still to touch, but not overly hot. This is probably good for cold camping either way to keep hands warm.

Like most other double wall titanium, it is not vacuum insulated so it loses heat faster than vacuum insulated thermoses and cups. But the double wall slows down the heat loss keeping the contents warmer longer and equally important, it doesn't burn your hands. Instead it will warm your hands which is often delightful. I really like the lid and I really like the slight flare at the top which makes it less likely to slip out of my hand. It sits flat which is more than I can say for my more expensive Snow Peak cup. Overall this cup is better than the Snow Peak (except weight-wise). I hope they make a 450 ml version someday with the lid and the flared top.

It does mostly what you were looking for. People say it should have a pour through lid?? No. Just gross. More place for things to foul up, or more moving parts to break or require sealing, which makes for more crevices for liquids to linger in. No thanks. A simple solid double walled robust Ti that fits great in the hand and cup holder. Just feels safe & reliable.

This cup is rated for 350ML. It's more like 400ML-that's filled to the brim. With 350ML of liquid, the lid still seats. If you use this with the lid, then plan on having less volume of liquid in the cup in order for the lid to seat properly. Speaking of the lid, my cup's lid came with a silicone gasket on it. When you put the lid on, it stays in place via the friction of the seal of the gasket. NICE! 'Bout time someone figured this out. SO, I put boiling water in the cup and started a timer. At the 10MIN mark I took the lid off and check the water temp, it was a 173Deg. At 15MIN mark is showed about 162Deg. The cup was set outside with the temperature at around 48F. The pressure of the steam would push the lid up while the cup was sitting. So CAREFUL- when you grab the cup! Look first to ensure the lid is not partially open - because if you tip it slightly while handling ... OUCH, that was still HOT! Better to open the lid, let some steam escape the reset the lid before grabbing the cup. The insulated cup worked GREAT! The outside skin of the cup was barely noticeably warm with boiling water just put in it! Add this cup to your light-weight hiking gear - you can have hot (or COLD) drink set aside while you cook the rest of your meal without having to worry it's going to cool off too quickly. All-in-all, I thought a good value for a piece of gear that fills a niche in my cook kit. FINALLY - A Decent Titanium insulated cup with a GOOD Lid! PS - Just for clarification ... all the pictures are pretty accurate except the lid has a gasket, and there are no external handles FYI. Also, the lid IS NOT insulated! Watch your finger tips with any hot liquids ! :-)

Great size, light and well Made, HOWEVER, this is not insulated and the heat of the liquid will pass through the walls of the cup. When using a hot liquid the lid will stay sealed closed. Great looking Ti cup!

This thing is made of titanium. It is very light and it’s double wild so hot or cold can go into it. It won’t burn your hands or in the cold situation. It won’t sweat and make a wet spot on the table top and won’t make a ring on the table if it’s a good wood table, it’s rugged tough and it’s good for camping.

I purchased a pair of these along with titanium filters from the same manufacturer for making pour over coffee as a camp setup for two people. Not many vacuum insulated titanium mugs out there! They are light and hold their temperature for quite some time. The filters fit and function. Overall, I will give four stars for lack of thought in that the lids do not offer some sort of option to sip without removing them entirely. Too easy to drop in the sand between drinks. Additionally, if the lids would work with the filters inside, they would pack far more efficiently.... just ideas. It is the little things, when it comes to the best outdoors gear.

Keeps my coffee hot and my chilled drinks cold Having a top that seals in the hot coffee is nice when try to sit down at camp. Note the lid isn’t going to stop a spill if it’s upside down but it does a good job of stopping what would otherwise slosh over

Very light and strong metal. Not leak proof, and is very prone to fingerprints

Lid gasket should be just a hair bigger. As is it doesn’t have enough grip and falls out to easily.
