Keith Titanium Ti3035 Plastic-Free Bottle with Leakproof, Quick and Secure Bayonet-type Cap Mount - 30.4 fl oz

I bought this for my son, it's perfect for his daily use at school, but I really it could be a bit smaller and fit into a cup holder in the car

This is a great titanium bottle. It doesn’t leak, is lightweight, and I can put it directly on the stove or in the fridge.This is single walled and not meant to be an insulating cup. The sleeve it comes with works fine to keep your hands from being burned or cold depending on the temperature of the liquid inside, but the sleeve is tight and a little difficult to remove. It also fits perfectly inside old oatmeal cans which does the job as well.Note that when exposed to sufficient heat, titanium turns a rainbow of colors. It is perfectly safe, and doesn’t damage the titanium at all. I heat anodized mine into a beautiful blue which will scratch off over time, but can be renewed with a second application of heat. The vibrant colors I was able to get mine to turn also let me know this is a high grade titanium, as promised.Mine has very quickly replaced both my kettle and daily water bottle. I can even cook meals in it! I will be returning to Keith for more of my cookware as I can afford it.Keep in mind when you first get it you will want to wash it a few times and let it sit filled with water overnight. Pour that water out the next morning, wash it one more time, and you won’t have any problems with taste.

Favorite? Did he say favorite? Geesh...Yes, I have a few: Vargo 700, Vargo BOT 700, Keith 550, and Keith 400.I like this one the best because of the cap and the wide throat. The cap is not threaded; it's best described as a bayonet mount: attach, rotate 1/4 turn, and you're done. So for fast access, nothing beats the bayonet mount. Is the bayonet mount secure? Well, I regularly fill it with water and ice and either tea or coffee, shake the crap out of it and--nothing, not one drop leaks out. I should say that if you're not careful, you can mis-mount the cap--clearly at an angle--and it will leak, so pay attention. Note that the water-tightness of the cap depends on the easily removable silicone cap liner. I hope there is an after-market cap liner available from Keith. There is a teensy-weensy hole in the cap (not the liner), I assume this is a release valve should the capped bottle be heated.The wide throat is perfect for ice, and makes it easier to see how much fluid is left.The bottle comes with an insulated sleeve, and a strap that is reminiscent of camping canteens. The strap can be removed, but I also removed the metal clips for the strap, which left a more streamlined package. The canvas-like, non-neoprene sleeve does a great job insulating my hand from hot and cold liquids. One drawback of the sleeve is its light color shows stains more readily. And only time will tell if the sleeve is durable.The sleeve has a drawstring that does a great job to keep the sleeve attached when the bottle is removed from a narrow water bottle sleeve in a backpack, a feature i miss on other sleeved water bottles.The only downside so-far is there's no way to attach a tether to the cap. Although I've left it on many counter tops, I've realized my error almost immediately. I would not want to use this bottle in any location where dropping the cap would be irretrievable, so I avoid roller coasters and surfing...

I really enjoy this water bottle. It’s extremely light, and nests with my snow peak 600 cup. The only issue I have is that the scraping noise it makes when opening and closing the bottle. Another issue is that if the cap doesn’t seat properly, it will cross thread and leak, which has happened on a recent trip. Other than that, it is a really visually appealing water bottle compared to my nalgene or yeti that I also own.

I wish this was double-wall insulated Titanium with the same design lid. The lid is particularly appealing as it accommodates tea bag strings while still being sealed fully. I ordered a silicone mason jar cover for my bottle, and it is the perfect combination however it took Herculean strength to get the cover on, with lubricant. The included cover is fine for use as a water bottle, I wanted these for hot tea.

I like how light the bottle is and it fits perfectly inside my toaks 550 pot. The look of the pouch is really nice & makes it easy to carry around. The lid is very easy to put on and stays on really tight on the bottle. I can't wait to take it with me on my fishing trips.

Overall this is a nice bottle but I had trouble with silicone gasket falling out if that were fixed and made this in double walled container they would have a real winner price is good though at 59.00 can’t beat that

Great product from keith, as expected. The silicone gasket system they seem to have is a bit different, but doesn't leak. So its aces for me. Fits my msr water filter system.
