"Good thermos. all stainless."
"I love my insulated thermos. I’ve been looking for something to drink coffee from that didn’t have any plastic. This bottle is perfect. It keeps my coffee very warm. There’s no leaking. The lid is just the right size for drinking from."
"Make a 20oz in this! I love that it’s plastic-free. We got one for everyone in the family. The 3 year old has a tough time with the outside lid, but it is tricky to get it threaded right. The 26oz is a little big to tug along…but it’s plastic-free."
"Love the look and feel of this thermos. Its definitely a little bulky compared to other sizes, but purchase the size relevant for your travels/situation. Quality is amazing and kept my coffee warm until the next day as advertised."
"Keeps things hotter longer than the traditional lid style"
"Solid construction. Keeps my coffee warm all morning. I don't know what the outside is coated with, so I don't drink out of the lid. Really happy with it."
"i've had this thermos for upwards of two years now. filled it with ice water, left it in a hot car in 95f+ weather, came back a couple hours later and the ice hadn't melted. filled it with hot coffee & forgot it outside shoveling last month, opened it up the next day a full 15/20 hours later and it was still steaming hot. i bought the white version despite that being a terrible choice because i'm a printmaker and anything white i own gets covered in ink very swiftly. somehow it has STAYED pristinely white, i've been able to scrub off all kinds of dye and ink stains regardless of how long they've been on, which is unbelievable. the only area where the paint/enamel coat has begun to chip is where i dropped a corner directly onto asphalt, and it's been, like, a year without that chip growing. it's great having a thermos that i know won't leave me with lukewarm coffee."
"Seems like an okay thermos, kept my coffee warm but for 1/10th of the time they are claiming. While I love open mouth designs I think the 360 pour 'feature' is just stupid and I hope you have your own office because if you don't use the 360 pour and take the lid completely off its metal on metal and loud, not playing with a Doritos bag annoyingly loud but in the ballpark. Going to guess that the other lids will cost me the amount I paid for the bottle and checking they are unfortunately the tkpro and tkwide are not compatible. I could do without the textured finish as well because I don't think I will be able to sticker it up. All in all worth the sale price? No, Since they are made in china like all the other crap on Amazon I'd say no. I won't be recommending or be buying another klean kanteen anytime soon."
"I simply love my new thermos. It keeps my coffee hot for hours, and the best part is that there is zero plastic. I would definitely recommend Klean Kanteen."
