How cool! The kind people at Certified Calm sent me my own Klean Kanteen! I’ve been eyeing this canister for awhile now because I heard it keeps hot drinks hot for 6 hours and cold/iced beverages or even ice cream for 24 hours. This is perfect for keeping tea/coffee hot throughout the day (or if you’re into smoothies, milkshakes, ice cream, or frozen yogurt, those will keep too), and the best part–you’ll be doing your part to help the environment as you won’t be consuming any single-use plastic/paper/styro cups. Since receiving my Klean Kanteen, I’ve been bringing it around with me whenever I buy hot and cold beverages. So instead of using disposable cups that immediately becomes waste when I’m done with it, I use this!

Its 12-ounce size makes it convenient to carry around, too. I can easily stash it into my bag and it also fits in my car’s cup holder (a must). But of course, if you need one in a bigger size, there are plenty to choose from. There’s an 18, 27 and even 40-ounce! And these are all made to last: Klean Kanteen is made of stainless steel, is BPA-free and has a lifetime warranty. So, if you think of it, its so worth the money because you only need to buy this once.

Here’s other things I love about Klean Kanteen:

* It has rounded corners. Containers with sharp angles are hard to clean, and it gives bacteria places to hide.

* It is BPA-free and has stainless cap options. There’s a wide variety of caps available for your Klean Kanteen, some are made with stainless steel and constructed with zero plastic. Others are made to clip onto backpacks, so they made great camping/hiking partners.

* It is eco-friendly and recyclable. These are designed to replace a lifetime of single-use items, plus stainless steel can be up-cycled (meaning it can be made into something equal or better). Just imagine how much good you can do for the environment!

* It is made with 18/8 food grade stainless steel. Klean Kanteen is constructed with the best stainless steel that can be sourced, and they are given an electropolished interior that does not contain a liner with plastic or baked-on epoxy. This means the canister will never retain any flavors!

* It has vacuum insulation. This is the reason for its uncommon thermal performance. Like I mentioned, it retains heat for up to six hours and lets beverages stay cold for as long as 24 hours! Pretty cool.

* It has a large mouth opening. This makes it easier to clean and can accommodate large ice cubes.
