Lightest Stainless Water Bottles

[dlee56]

Ran the Kean Kanteen last year, worked great. Steel does make a little more noise so just be aware.

Alright here's how these stack up.

Klean Kanteen 40oz (Un-Insulated)
Listed Weight - 8.6oz
Actual Weight (w/cap) - 10.0oz
Actual Weight (wo/cap) - 7.4oz

A good amount of weight that can be shaved off the cap. 2.6oz cap weight.

Again, a decent amount of cap weight. 2.4oz. Surprising that this one is lighter given it is insulated. A lot of excessive plastic on the Klean Kanteen top.

A little disappointed that the stainless bottles aren't particularly close to their listed weights. Will be looking for cap replacement options. Nalgene top did screw on to both but leaked.

I wonder what the Klean Kanteen without the powder coating weighs?

I've been thinking about going to metal bottles as well and found the Klean Klanteen 40oz wide mouth on rollback at Walmart for $11, so thought I'd play around with it. What follows is an exercise in gram weenie-ing and OCD.

My plain (not powder coated) bottle, without lid, weighs 6.87oz on my kitchen scale. So you save a little weight going plain steel.

The lid is the biggest issue as it weighs 2.6 oz (my scale agrees with Steve's). A Nalgene lid leaks, but almost any Hydroflask lid fits and weigh less than the stock lid from Klean Kanteen. I purchased a cheap pair of lids from Amazon (https://www.amazon.com/dp/B078T19RDY), which weighed 1.44oz as stock. I removed the little lanyard, since it doesn't function on the Klean Kanteen, and also removed the grippy rubber ring, since I think that's going to fall off sooner or later anyway. The stripped down lid now weighs 0.95oz. So the bottle+lid weighs 7.86oz.

A 32oz Nalgene on my scale weighs 6.20oz.

A Nalgene holds 5.16 oz of water per oz of bottle weight. The modified 40oz Klean Kanteen holds 5.09 oz of water per oz of bottle weight. When you look at it that way, you can get them pretty close.

Cool experiment, out of the box thinking there!

Of course, I just put a plastic lid on my metal bottle, so maybe this is all for nothing since I still have plastic elements in the setup. And as far as weight is concerned, we are still nowhere near a Smart Water bottle. But I have always been willing to deal with the weight of a Nalgene for the ability to put hot water in it, so that was the weight standard I was striving for.

Lol I think we're all just striving for reduction, knowing that elimination is almost impossible.
