I know water bottles are a weird thing to be picky about, but I am! I'd been looking for a glass bottle, but I didn't care for the design or look of the ones I saw on here until I found this bottle! It's exactly what I wanted. I like that it's a twist top and this glass is super tough, my clumsiness has already tested it against wood and concrete floors and no shattering! I was super impressed. I also haven't had any problems with leaking from the top. The sleeve isn't the most insulating fabric but it still gives the bottle a better grip and a cool look. I also love that it has a carrying strap instead of a clip, it's been easier for me to juggle a billion things and still keep my water bottle hanging off my pinky. Also, it fits in my cupholder perfectly! For anyone looking for a glass bottle that's unsatisfied with the ones offered, I highly recommend this bottle. They are a small company but I hope the grow fast! The owner seems like a great, hardworking guy and emails everyone who buys one to make sure they have a great experience, which I did! Pretty sure this thing is gonna last me awhile, but if life happens I would definitely repurchase this bottle!
