A Tantonka Stainless 34oz bottle weighs 8.5 oz w/lid. or ratio of capacity to weight = 4.0

A 64oz Klean Kanteen 64oz bottle w/lid weighs 12.3 oz ; ratio = 64/12.3 = 5.2

The 32 oz Nalgene ratio = 32/6.3 = 5.1

So there isn't much in it, with the 64oz Klean Kanteen being lighter per unit volume than the plastic Nalgene.

I don't think the weight difference matters unless you carry several of them empty. The water is most of the weight after all.

A difference of 6 oz is significant if you are carrying it in a pack,and there are perfectly good containers that are even lighter - recycled pop bottles and platypus containers. Shaving ounces from your gear, let alone pounds, will result in much less weight.

I think if I was gonna live and die by 6 oz I'd keep my SS bottle and just get a haircut before the trip.

Paying attention to things like the weight of water bottles can easily result in weight savings of ten to twenty pounds. Over the course of a week long trip that is considerable.

I first became interested in lightweight, serviceable gear doing SAR. Cutting weight allowed me to carry more items of use in the operation- everything from rope to stethoscope to additional dressings, IVs, etc. So yes it can be (at least in theory) a matter of life or death. I always got a haircut, as well. Don't forget to trim your fingernails....

Sure, shaving ounces on every item will add up. But I like to prioritize the items where saving weight is the most important and where durability is more critical. One of my most used PSKs is a Maxpedition bottle holder with with my AMK PSP, Mora, paracord and a few other survival items. In this kit the bottle really is the only area I'm allowing for more weight. This is critical since I can boil in it, it won't rust and it's very, very sturdy.

Interesting...I also use a Maxpedition bottle holder as the basis of what i call my NCOT kit (Nice Cup of Tea). I nest a Gatorade bottle and a Titanium mug, along with a very efficient windshield and a Trangia stove, plus the items for tea. it makes a nice compact unit and it readily produces that all important nice cup of tea.

The bottle holder I use is the one sized to hold a nalgene bottle with a pocket on the side and acres of MOLLE webbing all over.

I need to post pictures one of these days....

I think you did, Hikermor. Your posts were instrumental in me finally getting my kit right. Especially cutting the insulation out...couldn't make a good fit til then.
