Are you familiar with Klean Kanteen? It's one of the original companies that introduced consumers to stainless steel water bottles and other containers. I have been a fan since I was able to use their classic 12 ounce water bottle with a sippy cup tip, then change to a sports cap as my children got older. It is great at keeping beverages cold, a real plus (especially if you are toting milk in the bottle).
All their products are made from 18/8 stainless steel, contain no BPA (a lining commonly found in lesser quality aluminum and plastic bottles), as well as offering a lifetime warranty.
All three of my children have a Klean Kanteen and I take them everywhere: running errands, on trips, in school lunches. I keep them refilled and handy on the counter for quick water breaks. I actually think my kids drink more water because of these bottles (in a related article, read my article on the importance of water here).
I asked Klean Kanteen if we could run a back-to-school giveaway. They were kind enough to offer this beauty below: one of their classic 12 oz. "Kid Kanteens" in the color dew drop. It sports the newly designed sports cap, touted as being quieter than previous styles. As I perused their site while writing this article, all the fun colors in this bottle were sold out! So, it's a popular and hard-to-find item. The contest is open to residents of the USA and Canada.
