Back in 2009, I went disc golfing with a friend and while walking back to the car, I saw a dark blue nalgene in the grass. I was poor and in college and had always wanted a nalgene bottle, so I took it.

Today at work, I filled that dark blue nalgene up with water and drank the whole 32 oz over the course of the day.

its been a great water bottle for these past 14 years.

Get a good stainless one. Something with a wide mouth so it’s easy to clean, and from a good name like HydroFlask, Yeti, or Simple|Modern.

They are (mostly) dishwasher safe and they hold up forever. My yeti tumblers get used nearly every day for almost three years, get loaded into the dishwasher, and just show a little finish wear from scraping it with my keys or my wedding band.

My kids use Simple|Modern bottles and they hold up quite a bit more. The kid-style prints don’t last as long, especially with kids that drop and scrape them all the time. I have a SM one too (larger one) that has held up pretty good so far (and uses the same lids as the kids, but I’ve only got a year or two on it.

I buy aluminum exclusively, no plastic.

Plastic doesn't age well and isn't as recyclable.

Nalgene for life. Lifetime warranty, BPA free, and durable as all hell.

I've got a 1.5L stainless steel. It's got some dents, but it's still going strong.

Buy a hydroflask or other similar double walled insulated metal water bottle. They last forever (albeit with a few dents), you won't be ingesting plastic, and it'll keep your water cold for at least a full day.

Nalgene covered in stickers, as was the style at the time. Somewhere around 5-6 years old at this point? Been through quite a lot.

Maybe six months. I had a flip-top one for a few years, but I wanted a wide mouth

Have had my 330ml insulated bottle from a mystery brand for 7 years now. Paint is chipped and looks quite sorry in general, but I love it. I carry it around everywhere.

I also have a 630ml one from Quokka for very hot Summer days.

Lastly I have a 500ml Chilli's for my job, which I also use daily.

For cleaning the bottles, I suggest using those tabs that are sold for cleaning dental accessories like retainers. If you use something to scrub them from the inside you can create little lines that end up catching bacteria.

I've got a ~20oz Yeti vacuum stainless bottle with the small-opening screw-on top. I think I've used it for, maybe 5 years at this point? A long while. It's the right size for casual carrying at work and school, but I use a bigger non-insulated body when doing physical labor.

That poor yeti gets bounced off the back of ATV's, thrown in toolboxes, left baking in the car, all sorts of shit. It's dinged up and doesn't sit flat on a table but still doesn't leak so it keeps going.

It's a glass jug, so forever.

I use an insulated Contigo Autoseal bottle that I've had for at least ten years. It keeps water cold for quite a while. Its big virtue is that it closes itself automatically if I let go. I'm not all that clumsy, but I have dogs that sometimes decide to poke my hand unexpectedly.

Bought my current Simple Modern 24oz steel double-wall insulated water bottle over four years ago. I buy silicone sleeves for it to keep it from making too much noise and from being banged up, and I have bought many replacement lids (I prefer flip-top lids and they’re prone to breaking), but the bottle itself has been my constant companion over these four years.

It keeps ice water so damn cold all day long. I love it dearly. It is my emotional support water bottle and it supports me emotionally.

I have 2. 1 from previous work which I've using from past 3 years and the other I got when I joined the new workplace. Fuckers asked me to choose between a coffee mug or water bottle so I chose water bottle.

I didn't even think about it until now but I think it's been about 4 years on my work water bottle

It's metal and has lost a lot of paint and gained and lost a lot of stickers

Edit: At this point I don't even know the brand as that has also worn off.

I've had two Nalgene bottles for about 10 years, maybe more, and neither show any signs of quitting. They're big, virtually indestructible, and water filtration pumps fit on properly (for camping).

I have 2 nalgene water bottles that I use daily. Ones 20 years old, have bought a new lid a few times. It's pretty battle worn, but they're near indestructable.

I got an aluminium one off Ali Express with a metal unscrewable lid, because my previous metal water bottle which was meant to last me forever, had a plastic lid which broke. I've had it for many years now, and it's fine. A bit dented.

I recently bought a Sistema 500ml vacuum flask for like, $10 on a ridiculous special. It has plastic parts in the lid, but seems to be of decent strength. I really like it, I fill it with boiling water and then top up my tea for a few hours with hot water.

I've had my 1l Sigg aluminium bottle for about 10 years. The lid broke once when I dropped it and I bought a replacement lid. It's a bit dented but otherwise still good.

This is a surprisingly popular topic of discussion. We have five or so plastic Sistema 1L ones that we keep in the fridge. I think one of them at least is probably seven years old. Are we dying from tiny plastics? I don't know. Whatever.

My job got everybody branded hydroflasks ~3 years ago. I don't work there any more, but I pretty much never leave the house without that bottle.

My house bottle is a 1.5L Bubba bottle from Walmart. Had that about a year and a half so far and it is holding up well.

I've had my hydro flask copycat for more than a year now. I'm happy with it.

I have many water bottles, most of them had at a great price from Costco. There is a some variety but they are mostly Takeya/ThermoFlask 40 oz vacuum insulated stainless steel bottles. I also have a couple gallon stainless steel vacuum insulated water bottles that are great for camping and travel. Those were sold as growlers, I think. I've had most of these for >5 years. This is one area where I'm doing buy it for life and it's going well so far.
I also have a 10 year old 1 liter un-insulated steel water bottle that I keep in the fridge. I should probably replace it but it still works.

Please stop using plastic water bottles. Especially, but not only, disposable plastic. Not only is it bad for you (microplastics), it is bad for the environment.

ETA: I just went to Costco tonight and those Thermo Flask bottles are on sale: 2 for $20, which is a great deal.

Bought a 360 Degrees 1 litre stainless steel vacuum one from a hiking shop. 37 Euros. I could keep water cooler by storing it in my armpit. It's absolutely fuckin rubbish

Emailed the company, ignored. Emailed them reminding them they'd ignored me, ignored

Definitely won't be buying their overpriced shit again

I have a few bottles which ranges from 1-5 years old. Mostly plastic of the brand Camelbak. They are good, and I don't know what more to ask for in a water bottle. However, more often than not I just end up reusing an old soda bottle.

Insulated Klean Kanteen. It's got about nine years worth of debts and scratches.

I'd like the bigger capacity I could get from a non-insulated bottle — as I really don't need the insulation anyways — but I have become sentimental towards this old thing.

About a year. I found it after cleaning up an event. Took it home, soaked it for 24 hours, and now it's covered in stickers.

I occasionally buy soft drinks. When I'm done with it I reuse it as a water bottle until I buy another soft drink.

I've been using a Nalgene 1L daily since receiving it last Christmas. It has the screw on widemouth lid, I'm typically leery of any plastic, but I feel safe with this particular brand that is made in the US (where I foolishly believe that material sourcing is better researched).

7 years I think. Big chunky metal thing.

I've had a flip-top zojirushi for more than 5 years. It replaced one of the same, the lid eventually cracked after about 6 years from being dropped so many times. This one has been dropped less. I have a new one in the pantry for when this one eventually dies. It still insulates as well as the day I bought it and the flip mechanism is just as satisfying.

My criteria: pocketable (not huge diameter), insulated, covered to keep work dust out of it. Sometimes the metal bottom gets a bulging dent when I drop it, I use a hammer to flatten it back out.

Just reminded me to replace the one I have. Bought it at Decathlon, one of their store brands. It has a cap with an opening mechanism which didn't last for very long - like 4 months of daily use.

I will lose every water bottle that I brought out of my home, so I just reuse the bottles of bottled waters. If I dont lose it, I will replace it every 3-5 months depends on the usage and weather.

I have couple durable, metal, and dishwasher-safe stanley and hydroflask bottles at home. They should be couple years old, but I am not keeping count.

I've got a 0,7l steel bottle from my ex-company 3 years ago.

I have a 1L TAL bottle from Wally World. I’ve had it about 3 years. Granted I don’t use it much. I use it when I go deep forest fishing. I fill it up with water and ice. Then clip it to my backpack tackle box. The poor bastard is beat to hell. It’s dented and some of the paint has chipped off where the dents are. But it holds water, and keeps it cold.

I bought a Hydroflask 6 years ago. It's got a small dent on the base that makes it not sit perfectly flat. It's bright green and I love it.

5 years with my Litre Yeti, going strong. When I drop it it tends to dent the ground not itself

It's been a little over two years now since I orded mine off amazon. My kids drink out of it everyday because they know I always have it filled up with water. I love mine and take it every where I go.

I've got several ikea glass water bottles because i tend to forget where they are. They're pretty simply made (glass bottle, plastic cap, silicone ring) and therefore easy to clean.

They've held up well for a few months now.

At least 15 years. It's kinda dented but it still works, what do I care. Mountain Equipment Coop has really good products.

I have a couple of cheap no-name screw top steel water bottles I bought from a Kroger almost 20 years ago for like $3-ish a piece. I bought them solely because the bottle part was one solid piece, and they didn't have any of the weird plastic clearcoat a lot of steel drinkware has, which meant I could boil water in them if I needed to when I was up camping or hiking. A lot of other more expensive bottles being made at the time were two or three pieces press-fit together, and wouldn't be likely to survive much of that.

I've been using them daily more or less constantly since then. They're a little banged up, but still going strong. I wish I knew where I could buy more.

1.5l SIGG for about 20 years.
