The Keith titanium water bottle is by far the best find I've had on Amazon! I don't think this review will do it justice, but I'll try my hardest.Unlike most water bottles, I'm loving this mini size. I try to carry minimally here in NYC, so I avoid carrying bottles of any kind. Being that this bottle is titanium (Proper Titanium), and it hold less than 20oz, it is an absolute dream!!!!!The entire thing is titanium, including the lid and attachment hook. The cozy is not titanium, but it does offer a snug fit and a YKK zipper!!!!We know titanium is not cheap, and I admit I have a titanium obsession. It's lightweight, extremely durable, and one of the sexiest metals in the world (to me). Not all titanium is made the the same, but this bottle emits alpha titanium pheromones! I'm in love.All of that aside, this bottle lends to a perfect every day carry with a tactical element.I am a bit confused about how to wash it. It said hand wash, and dishwasher safe. To be on the safe side, I will definitely be hand washing this bottle.I can't recommend this beautiful bottle enough!It's worth every penny!!!!!!
