A few things about #Nalgene bottles for #backpacking #camping #trekking #outdoors:

The polycarbonate 1 L bottle weighs 176 g. The HDPE version is cheaper and weighs 110 g.

HDPE will be leakproof up to 150°F as a hot water bottle to heat your bedding at night. 100% boiling water will burn you and cause leaks.

Mix 500 mL 100°C (boiling) water with 500 mL 20°C water to get 1000 mL of 60°C water (140°F). Adjust for ambient temp.

I've done this every night for a whole Winter, zero leaks.

For backpacking and not hot water consider moving to something like an Evernew 2L water bag. 42g and holds 2 liters. Very tough and fits a Sawyer filter directly. It gets smaller as you use up water.

For filling with hot water car camping try something like:

You can put in as hot as you want and can drink the water later. With Nalgenes and hot water I worry that plastic has leached into the water

Nalgenes still make good pee bottles

P.S. In the very cold weather if you use a hot water bottle to warm your sleep system if it leaks you can have a serious disaster.

@HikerGeek I have lived through an entire Northern New England Winter with temperatures down to -25°F and wind chills down to -50°F using a Nalgene HDPE bottle as a hot water bottle in my bed. I have never once had a Nalgene bottle that was properly closed leak, ever. I trust Nalgene bottles with my life and with actually dangerous contents.

Didn't mean any insult to you or Nalgenes.

Just offered that there are more modern alternatives that may have some advantages over Nalgenes.

@HikerGeek That's great, but I'm speaking specifically of Nalgene bottles. I'm sure you will probably realize that I am fully aware that other types of water containers exist and have their own advantages and disadvantages. My post is about Nalgene bottles, not about the best way to carry water.
