When it comes to adventuring: there’s nothing worse on a hot summer’s day than opening your bottle of water, taking a swig, and burning your tongue! In contrast, there’s nothing worse on a cold winter’s day than setting yourself up for an amazing hot coffee after a night of camping in the rough, only to find the coffee is like ice. The Klean Kanteen eliminates both of these issues! It’s an amazing invention: keeps cold drinks cool for 24 hours, and hot drinks hot for 12 hours minimum. The best part is: it works. I tested the 936ml bottle – and of course I had to make sure it worked in all kinds of situations. It’s been on the boat for some overnight fishing; in the forest for some hiking; taken to a job site for a tradie to test out on a hot, sweat-filled day; and let me tell you – it was perfect in every situation! The bottle is 18/8 stainless steel, environmentally friendly, and fitted with vacuum insulation technology that helps keep the heat or cool in.
