Klean Kanteen Review

Klean Kanteen Wide 40 oz. single wall water bottle I've had my Klean Kanteen Wide 40 oz. single wall water bottle since 2008. It's not sexy, it's not expensive, and it's not the item that most gear heads would ever brag about. But it is reliable, durable, and trustworthy. Exactly what you want in a backpacking partner.

Of all of the backpacking and camping gear that I have bought and used over the last thirty years, I can easily say that my Klean Kanteen has been the most used, most reliable, and best value of all.

When I first purchased it, I was looking for a water bottle for winter camping. I wanted a bottle that I could melt snow in as well as to store water. Most people will melt snow in one of their cooking pots. This is fine but why not use another vessel separate from the cooking gear?   It seemed like a simpler solution with less chance of spilling water and wasting fuel.

It would also serve the same purpose of plastic water bottles like the several Nalgene bottles that had recently been recalled due to BPA contamination. Among winter campers, It's also a common practice to place a hot water bottle inside your sleeping bag to help keep you warm. It's imperative that the bottle must not leak! It made sense to me to have one container that I could use to melt snow, store water, and also use for a hot water bottle. Better yet, a stainless-steel bottle should be nearly indestructible.

It's important that you do not use any insulated or double wall Klean Kanteen, or any other brand, to heat water in as it could explode or rupture. Only use single wall vessels to heat or boil water!

Since buying the Klean Kanteen, I've used it most every day. It replaced the Nalgene bottle that I used to carry to work. It's also virtually eliminated buying bottled water.

The wide mouth screw cap has a loop for easy carrying. It can be secured to your pack with a carabiner. The threading also fits many water filters or purifiers.

The cap has a silicone seal that has held up perfectly for the last twelve years of nearly daily use. The only leaks that I've experienced have all been to user error. The cap doesn't require brute force to seal either. Just a snug twist should do.

A nice benefit of stainless steel is that it doesn't impart any flavor. No plastic aftertaste, just water or whatever you happen to store in it. This also means that you could use it for wine or beer. Other beverages should be fine too!

It has held up to twelve years of nearly daily use despite occasional neglect or abuse. I have dropped it a few times, and it has a couple small dents in the bottom and a number of minor scratches. It's brushed stainless still finish hides these minor scars. I've left it in my car on 100-degree days and the plastic cap and silicone seal works like new.

Compared to a standard wide mouth Nalgene bottle, it is slightly heavier, but it also has an eight-ounce larger capacity. It can also boil water and even pound tent stakes in a pinch. Don't try that with a plastic bottle. When I'm looking to save grams when backpacking, I'll use my Platypus water bladders and used Smartwater bottles.

The bottom line is that the Klean Kanteen has served me very well and would not hesitate to recommend it. I got mine at REI.
