Go Light – Ditch Your Nalgene Bottles

A 32 ounce Nalgene bottle weighs 6.2 ounces
A one liter Nalgene bottle weighs 6.2 ounces

Whenever I see a backpacker carrying wide-mouth Nalgene bottles, I cringe, because I know that three of them add 15 ounces to the weight of their backpack that could be easily eliminated. For example, a one liter wide-mouth Nalgene bottle weighs 6.2 ounces, empty.

If you want to save some money and some pack weight, empty soda bottles make good water containers for backpacking. This empty liter bottle of Pepsi only weighs 1.2 ounces and cost $0.99 cents at a gas station. Granted, soda bottles have to be replaced more frequently than Nalgenes, but you probably buy enough bottled water or soda yourself or know someone who does, to get a regular supply of these bottles whenever you want.

The only real functional limitation of soda bottles is that they’re no good for holding hot water, but if you need that capability switching to a Platypus reservoir is an even more weight efficient alternative.

A 2 liter Platypus bottle weighs 1.2 ounces
A 2 liter Platypus bottle weighs 1.2 ounces

For example, a 2 liter Platypus reservoir  bottle weighs 1.2 ounces and a 3 liter Platypus weighs just 1.5 ounces. Both are safe to use with hot water, stand up by themselves on flat surfaces like regular bottles, but fold up flat when empty.

Whatever you decide, ditch your Nalgene bottles. They’re just not worth the extra pack weight.

  2. All of these are full of bisphenol-A which is an estrogen mimicker. Only titanium for me, no slowly turning this guy into a high pitch voice, low testosterone, masculine deficient, androgynous humanoid.

    • you know very little. The dose determines the poison. FDA has strict requirements. Just because your detect trace chemicals after an extraction experiment doesn’t mean there are enough chemicals to cause concern. GCMS is very very sensitive.

  3. Not sure how simply opening a bottle will cause it to start degrading. Sounds like scare tactics to me.

  4. no they don’t contain bpa. they do contain other estrogenic compounds, but then again so does your nalgene: http://www.npr.org/2011/03/02/134196209/study-most-plastics-leach-hormone-like-chemicals

  5. I agree. I hear what everyone said but punctures are a real thing on a any trail. I do not not want to leave my safe hydration to something My own knife could go through. Water is the second to me , right after shelter. On a hike water is NUMBER ONE. My Nalgene has been so useful for all kind of reasons, and is only full on the last trip back from getting water. I use it for my steri pen. I have a filter down to 1 micron but I like to be on the safe side as to what I worry about IS one micron. So. filter, pour to Nalgene, steri then into bladder. Everything is full on last trip but all ready to drink except last bit after nalgene is emptied. I never ran out of water and never felt bad from water. Water weighs a lot so I try to manage only what I can add to my full pack weight Just in case the Most water I can find for a bit is at the beginning. I am currently using GRayl as my filtration. easy to use and dependable.

  6. The Only reason i see to take a nalgene over a wide-mouthed soda bottle is the hot water bottle. There’s no reason why a hdpe version couldn’t do this just as well is there?

    I don’t want to be a gram weenie but I don’t see any reason to carry unnecessary weight. Carrying enough of that already.

  7. Actually, they can be used as hot water bot water bottles. But, you cannot fill them with boiling water. Up to 160F is safe enough. Boiling water can pose a leakage and burn threat. You really don’t want to sleep with it. It is too hot. It is easy to burn yourself if filled with boiling water. 160F water might burn you, but not badly. A better solution is to wrap a hot rock in a bandana/hiking shirt or other clothing. It holds heat well and is NOT wet in your bag. Small pebbles can be used in a sock. (Sand makes a mess.)

    • This is a good point. I was just in the Adirondaks last week at -10° and a +15° sleeping bag with an added liner. With all my layers and jacket i was ok, but not as warm as id have liked. I boiled water for a nalgene inside my sleeping bag. I double and triple checked the lid and it still leaked. Boiling water can cause leaky bottles. Only thing worse yhan cold is cold and wet! If i was wearing cotton, id probably be dead. Fortunately i knew enough to wear wool, fleece and synthetics with a downtek fulled bag. I woke up partially wet, but i was wark enough due to the material of clothing. As far as hot rocks, i would typically agree, but in the eastern Adirondaks, fire is not allowed, only small backpack stoves, which would be less than ideal trying to heat rocks. Moral of the story, dont ever wear cotton.

  8. I always carry large Smartwater bottles. One good thing about wide mouth bottles though, is when you plan to use a SteriPen.

  9. When backpacking with my boy scouts, I insist that one of the bottles they are carrying is a nalgene like this. All of the others can be as light as possible. Reason? They can’t destroy or poke a hole in the nalgene.

  10. I hate to be a stickler but 3 Nalgene bottles at 6.2 ounces each is a total of 18.6 ounces, or more than a pound just for the bottles alone.

  11. I’m with Philip. While Nalgenes and bladders have their uses my regular 3 season kit is 2 (20 oz./591 ml) Smart Water bottles and the 2L Platypus. Light, cheap, tough and the caps are interchangeable. As for potential punctures, who isn’t packing duct tape, urethane or equivalent?

  12. Actually I’d rather carry the extra weight than support an industry (plastic water and soda bottles) that does so much harm to the environment.

  13. Thanks for sharing, Phil! To your point, Nalgene does make a soft bottle called the Cantene if you like the convenience of the wider openings and connected cap. Although a tad heavier, these puppies weigh in at 2.1 ounces. Their other HDOE bottle weighs in at 3.7 oz., still ‘way’ better than their heavyweight.

  14. Excuse? But I want the Wide Mouth bottle. Answer,…. Hydrapak Flexible Bottles. http://hydrapak.com/shop/water-bottles/ PACKS SMALL when not in use. Small to WIDE!!!! Mouth choices.

  15. GatorAde or Powerade bottles have wide openings and are stable and almost as light as water bottles. I prefer Powerade bottles and White Cherry flavor didn’t leave any oder. I only wish their caps were not black. I’ve had issues with GatorAde bottles smelling forever but maybe I didn’t find the right flavors.

  16. Meh to soda bottles. Brittle, thin plastic. Drop a full one on some rocks and see what happens.

    Amongst the options to the Nalgene polystyrene: Polyethylene Nalgene quarts are 3.8 oz. And now they make various Cantene collapsable containers which are a durable, softer plastic. And there’s also the Hydrapak collapsable bottle. Even with those options, i still carry at least one wide-mouth Nalgene to use for mixing powdered electrolyte replacement drinks. (Current favorite combination is Vitalyte with some dehydrated coconut water.) These are easier to mix in wide-mouth bottles, and wide-mouth bottles are easier to clean well.

    No cringing needed on my account.

  17. If you ever do winter camping or hiking or snow sports, the benefits of a wide mouth of a nalgene should be familiar.

    Why buy a different bottle for different seasons?

    If it were me, I’d get a wide mouth stainless – can scoop snow, can be used to heat and melt it and it works in any season.

    Leave the used soda bottles full and unpurchased at the store where you found them.

    If you are complaining about a few ounces of weight in your pack – hit the gym.

  18. Philip,

    For us winter hikers & climbers, what type of bottle coozie do you use with the Platypus bottles to help prolong freezing? I’ve been wanting to do this, but haven’t found a coozie (40 Below, OR) that the Platypus fits in efficiently enough.
