Edited 09/2019 to add some more info after a few real world camping trips.After taking this camping a couple of times I am still very pleased except for one thing. The lid for the cup ended up warping slightly after getting too hot. I would sometimes place the cup in the fire with the lid on to boil water. One time the lid came off and went straight in the coals. I did not think anything of it, and fished it out after a minute or so. I later found that the heat had caused the lid to warp slightly in the middle. This meant it would no longer fit snugly in the cup and would pop off.I eventually had to bend it back slightly, but it was not as perfect a fit as when I bought it. Will contact the seller to see about a replacement and post updates. UPDATE: The company was more than happy to send me a replacement lid for the cup free of cost. And yes, the canteen has developed that lovely "blueing" titanium gets. It now looks beautiful.Dropping $150 on a canteen mess kit seems foolish, but then you have to remember that when it comes to camping equipment, you should only have to buy it once and then keep it for the rest of your life. This is no exception.First of all, it's titanium so it's light as hell and tough as the devil. The canteen has a nice wide mouth(Good if you want to add ice cubes or use a water filter), and the silicone o-ring in the lid(which has a carrying ring) makes sure it doesn't leak. The cup has a nice two piece handle that locks ever so slightly off-center, and the lid that comes with it fits so snugly that you can fill the cup with liquid, turn it over and the lid will not come off. It's not watertight so it will leak slightly, but that's not the point. the point is to keep the lid on. A lot of titanium camping gear and cookware that have lids usually fit flush but snug enough to stay on and so will fall off if jostled or moved(Looking at you, Toaks!). Speaking of which the lid has a carrying ring on top. This is so that if you wanted to lightly place the lid onto the cup while it's on a bed of coals, you can use a stick to lift it up to see if the contents are boiling. Well, I did a little test and if you are careful and the lid is placed on tight, you can lift a full cup just by the ring on the lid. Again, it's not foolproof, you can't just yank it around and hope for the best, but used with a light touch it is a nice touch.So far the bag that came with it seems solid enough and the belt straps are thick and durable. There is an inside extra strip of nylon fabric that goes around the inside middle for extra strength. When the complete kit is placed in the bag and on held on one's belt, it's quite easy to undo the clasp, flip back the holding straps and lift the canteen out of the bag for easy access, leaving the cup at the bottom of the bag.The straps were stiff at first, but a few minutes of kneading and stretching them, they 'gave' a bit more. There is a pocket on the inside of the bag to hold the lid for the cup. The most minor quibble I can think of is that the grommets holding the belt straps to the bag are not covered by fabric on the inside, and will probably end up scratching the finish. It can easily be remedied if you care to with some stick-on felt pads, but let's face it: Camping equipment should show wear and tear and you should not allow yourself to be bothered by it.The shoulder carrying straps are adequate. They're not the thick nylon webbing that the belt loops are made of, but that's OK as well, it would have been overkill and merely added more weight. As it is, I'll probably just use the belt straps. There is also no rattle whatsoever when the entire set or just the canteen is placed in the bag, empty or full, something which I very much appreciate. If I'm outdoors enjoying some peace and quiet the last thing I want to hear is a clinking or rattling. The bag is the only thing I can see eventually needing maintenance with extended use but so far, so good. If I have any issue with it I will amend my review but for now I am EXTREMELY pleased.Incredibly light, incredibly durable, understatedly stylish enough so that it doesn't look like something for, as another reviewer on this item stated, a "Mall Ninja" or "Paul Blart: Rugged Outdoorsman And Stoic Veteran Who's Seen Some THINGS, Man!". This is something I could put in a carry on for long flights or bring to work and not look like I'm writing a manifesto in my Montana cabin during.my spare time. I'm looking forward to using this on a campfire and seeing the titanium finish acquire that beautiful blue-ish rainbow hue once it oxidizes.I didn't receive this as a gift or a promotional freebie for this review, I dropped a hundred and fifty bones on this by myself and buyer's remorse is nowhere in sight. I have a nephew in the UK who's coming over here to travel around the states for his gap year and I am already considering buying a second one of these for him. It's that good.
