Klean Kanteen Insulated Classic 32oz

This was not the lightest item in our pack. Let’s face the facts – it’s a stainless steel, vacuum sealed container. One that allowed us to keep freshly filtered, cold spring water in a frigid temperature range as we scrambled up south facing scree fields in direct sunlight. The cold water was a religious experience while grinding up Sawtooth Mountain passes.

This powerhouse of a water bottle keeps liquids hot for 24 hours and cold for 90 hours. That’s a 9 and a 0 combined there, folks. It was worth every weighted step carrying around all 14.9oz. The leak-proof loop cap works like a charm, maintaining a completely leak-free trek, thankfully, because a leaky bottle is the worst type of annoyance.

This iconic piece was the first launched product by Kleen Kanteen. And we don’t see it going anywhere, anytime soon. If you like a little style in your hydration container, this one comes in six different colors, two of which are matte.
