Review: Everything we were looking for - This titanium bottle went on it’s first 10k in the mountain canyons yesterday and didn’t leak a drop. The lid is easy to get off and on but I apply a bit of downward pressure to help the silicone seal to seat or unseat. This 18.6 fl oz bottle weighs 2.5 oz less than the stainless 16 fl oz bottle that I’ve been using. It nests nicely with an MSR 400 ml titan cup with room to spare so a paper towel can be wrapped around the bottle if desired. Various drinks can be mixed up in the cup letting the bottle carry only clean, pure water. This the biggest bottle that fits standing up in my Mystery Ranch Hip pack with a Patagonia Houdini and a handful of essentials, perfect for trail hiking and canyon walking for our favorite 10k jaunts. The bottles are certainly high quality and priced very nicely compared to other similar bottles of lightweight and good looking titanium. We did a backing soda soak followed by a vinegar soak to get the normal manufacturing smell washed clean. Now we can’t taste anything but clean, pure water.
Review: Lightweight & Durable - Lightweight & durable. I wish I had bought this years ago. I bought it to replace "single use" plastic water bottles that I would reuse for a month. The plastic ones would stink up fairly quickly at the opening. I cannot figure out why, but my titanium bottle takes a VERY long time before it starts to smell. So if you are lazy about washing your daily water bottle like me, get this bottle! For backpacking, I still bring two 1L size SmartWater bottles, but for daily use, travel, and camping, this bottle is great because it is so lightweight and durable. I drop things with some regularity and this bottle is a tank! That it fits neatly in my small crossbody purse is a bonus. Due to its titanium construction, you can remove the cap and set it near (not in!) a fire or stove to thaw the water inside in case it froze. Be sure to rotate it to ensure even thawing. Also, you can put in hot tea , that otherwise might melt your plastic bottle! Just be sure to hold bottle with gloves or mittens because it is NOT insulated -- hot water inside = hot bottle outside. In case anyone was wondering about filling it with alcohol, you can do that too. I premixed a cocktail and brought it on a weeklong canoe trip. Titanium is very nice for this because it doesn't change the flavour of your drink, unlike other metals. I learned my lesson after putting expensive scotch in a Stanley flask..! It does not leak as long as you do not under or overtighten the threads. I have had one person use my bottle and it leaked because they didn't pay attention. I don't normally pay attention either, and I don't get leaks, but it is worth noting. If you are concerned, you can always shake it upside down to see if it will leak. The only negative I can think of, for my purposes, is the price. It's what kept me from buying it for so long, and what keeps me from buying one for each member of my family ;-D I love this bottle!

### ⭐⭐⭐⭐⭐ Fantastic lightweight water bottle!
*by E***A on December 12, 2017*

Not the first Keith Titanium bottle I have purchased, and I suspect it will not be the last either. Great bottle! Incredibly lightweight, portable in any position because of the leak-proof cap, and made of super healthy titanium, which means no leeching of harmful chemicals.
