Perfect fit for my son and daughter's lunch boxes! We use these everyday! I love that my kids get 12 oz. of fresh pure cold water at lunch while at school. These are so much better than plastic bottles for so many reasons. 1. Plastic is toxic. 2. Plastic is not earth friendly. 3. Plastic is not insulated and does not keep their water cold. The list could go on and on. Also, they are easy for them to unscrew (a problem we've had with other bottles in the past). And they don't leak (also a problem we've had in the past)! We own 6 Kleen Kanteen bottles and love every one of them!Nice bottle. I will use to prepare a meal replacement smoothie every day.It has a solid build and it really is insulated.Easy to carry on a handbag or messenger bag. The weight is what you expect from an insulated bottle.Perfect for hot or cold liquids. I bought it to put in my mini backpack when I go to theme parks, and it's the exact right size!I like this bottle and is well made. Beware when ordering to specify the color you want - I actually wanted the orange one - my bad.And it has not yet been sold in their own country, I bought here. Doing a insulated classic type! Is a little big, but I have been working every day. Ease of use and robustness, and design! Is a big fan of this product. Also it will cheer from now.Best insulated/vacuum on the market. Wide mouth cafe cup version is even better.My son loves his water bottle, that's great because he's drinking more.We are going to moget rid of all the other water bottles...and be a KK familyGreat for my 5 year old son, first time he used it was on a field trip and it kept ice the whole time in the 95 degree Florida weather even with multiple fills.I love KKs. I got this for my mum for Mother's Day and she likes it. Just the right size for her handbag. However I do think this particular one from this seller is over priced for the sized but I wanted this colour so had to pay the extra.This is the third INSULATED KLEEN KANTEEN I've bought, which says something in it's self. I bought this one, to supplement the 20oz widemouth which I use mainly for hot drinks when travelling. The smaller one will be used to hold cold drinks mostly, on shorter trips and also to give a choice between hot and cold on longer trips. Like all KLEEN KANTEENS, pricey perhaps, but well worth the added cost when one considers the quality and how long they last, and the incredible performance, be it with hot or cold liquids. Well worth the added cost and flexibility of the insulated Kanteens .Definitely recommended! ( the non insulated ones are also worthwhile, just not quite as versatile, and I've three of those as well! ) ....I was surprised just how cold my water stays in a hot environment. I'd recommend getting a larger one for most people, but this one is great for hikes where you are carrying water separately and can refill a water bottle for drinking on-the-go. Also keep your morning tea nice and warm =)Best purchase for kids in school or camp. Really does keep their drinks cold. Never tried it with hot beverages tho.Good bottle!
