On hikes I use a water bladder that goes in my hiking backpack. I add a lot of ice cubes and it keeps my water cold for six hours. I also carry back up small water bottles half frozen half fresh water as they melt enough to use if I run low for myself or the dogs. In the car is where I leave a giant insulated water bottle waiting for me to rehydrate again if I ran out of water on a hike.

I feel like an insulated water bottle would be too heavy especially a large one to hike with.

Hydro Flask with the Flex Chug cap. Keeps water cold and it doesn't leak.

1. Freeze a one litre Nalgene bottle 1/3 full of water to create a block of ice.
2. Top off with water before your hike.
3. Put in a insulated Nalgene carrier, or something similar 👇

The carrier also keeps a bottle of water from freezing in the winter.

Smart water bottle and sawyer squeeze filterif you’re near water sources. Fresh cold water as much as you want.

There are lots of insulated bottles in thrift stores, that's where I've picked up a couple.

If you’re trying to cut weight then it’s tough to beat a sawyer squeeze paired with two 1-liter smart water bottles. In addition to that I bring a CNIC vecto water bag. If it’s a day hike or easier backpacking trip I bring the Grayl water purifier and 1-liter water bottle.

Depending on the destination, I bring anything between a 600 ml bottle and a 3L hydration bag plus two 1000 ml bottles. The weight of the bottle is not something I pay attention to, as it's so overshadowed by the weight of the water itself.

I have an old, heavy but very effective Katadyn Vario filter. I love it. It's made to last, the active carbon reduces tastes in addition to the fiber and ceramic elements giving clean water, and spare parts are available - I don't like the attitude of 'just ditch it and buy a new one'.

I think I carry more than most. I have a platypus gravity filter. I think it’s a 3 or 4L dirty water bag. I carry a 3L bladder in the pack, 3L camelback, and a 1L smart water bottle. I also have a 20oz hydra flask that’s mostly for coffee but I’ll fill it too when I fill. I also drink a gallon of water a day when I’m not hiking so between drinking and cooking, I go through it. However, I like to have plenty of water on me and know I can ration it and go longer before I have to find water again. Plus I go up and down mountains (hunting) and most of the time what you got has to last cause there isn’t water up high and you may have to drop 2k to refill. More water I got the longer I can stay and hunt without having to drop back down to refill. I won’t leave the trailhead without 3-4L at a minimum even if I know there’s water available. Again, I carry more than most but I’m not gonna find myself out there all dehydrated wondering around praying for a trickle coming out of the rock somewhere. Water sustains life, sore shoulders and legs goes away after a few days.

Smart water bottles (at least bottles that shape from aussie supermarkets) and a katadyn befree filter.

Saywer , 2 1 L smart waters but I do carry a 3rd jus in case but I’ve learned my technique

When I refill I hammer water I sit by the water source refill and drink as much as I can without getting sick of course . Then refill again so I have around 3L

The other tip is honestly map study if you’re certain you will have water sources every 6 miles or so I’d carry 1 -2 L if it’s the desert part of the PCT or dry parts of TRT…yeah I’m carrying a lot and more lol

The insulated Kleen Kanteens are really easy to attach with carabiners.

I use Nalgene but got a neoprene sleeve for it. Although I don't use the carabiner, and just put it inside.

I made a water bottle with a built in forged carabiner because I had the same problem. Attaching a carabiner to a normal insulated water bottle adds a lot of additional swing, they aren't built for quickly attaching to gear without snagging, and because the carabiner isn't integrated it flops around when not attached. We solved these problems with a custom carabiner that won't snag or flop, and in doing so added additional lightweight insulation to keep drinks hotter or colder for longer. Obviously, this is my product, but I think it's a better solution than anything else on the market. Check us out at carabinerbottle.com if you're curious. I'm also happy to answer any questions you might have!

I was there for three months last summer and made great use of a lifeStraw water bottle. It doesn’t get much colder than being able to scoop it right out of the waterways. Lol just don’t use it in the geyser areas!

I have a hydro flask that works great, keeps water cold all day. Bit heavy, but works for day hikes. If backpacking I’d just use a nalgene

Camelback of some sort, all day long.

Long walks and runs is totally different right? Unless you run very very slow. You will want more of a soft flask for running, I would never take a metal bottle or something it will hurt over anything More han 5k probably if not just inconvenient at best. For long walks anything goes and you can search on Google for metal like bottles which will last. Thicker the longer but also increases weight

For running I would rather recommend a Camelbak. You could use the same for hiking, it provides enough space so you can tuck in your housekeys, your phone and perhaps a cereal bar even. 

It’s not a necessity for walks but for running it is definitely the recommended way to bring liquids with you!

edit: I have just noticed they also sell bottles. I am talking about their mini rucksack with the bladder, the brand is Camelbak but product is called Hydrobak and I have a 1.5 liter version of that which I use for half marathons.

Get the non-clear Nalgene. It's pointless to have insulation unless you continually have iced water imo.

Project farm did a test on some reusable bottles. https://youtu.be/a6j1NJkNzwI?si=YoXy5kczFXonptN6

Hiking backpack with a water bladder. Holds so much more than any bottle will(that can easily be carried around the park) and you’ll be hands free.

We took Camelbaks, saw lots of hydration packs and reusable water bottles being used. Park was quite hot last week so expect to drink lots of water.

They reported Cyanobacteria in the water of the park so recommendations are against filtering water on the go, so your best bet is to carry water with you.

Old school nalagene

Water bladder

Smart water bottles, even if I'm not backpacking I still always use them. Good size, lightweight and slim so easy to stuff into packs.

Nalgene and other ones are the kind I keep around home or the office but feel to cumbersome for outdoor activities imo.

lightweight, easy to replace, hard to break, and works with filters. Tall and thin also means its easier to take in and out of your side pockets or fit multiple bottles in one pocket if you need to

Its how to spot thru hikers...

• Nalgene bottles - Probably a weekender
• Beat to hell Smartwater bottles - Yup, that's a thru hiker...

Edit: Friends, its just a joke...

Same thread size as many other products such as Sawyer filters and Platapus collapsible water bottles. Lightweight and easily purchasable if they break. More robust than a standard plastic water bottle.

They fit the thread pitch of the sawyer filters perfectly. Also the sports cap can swap with the sawyer mouthpiece and it works really well.

Zpacks, Altra, Enlightened Equipment, ect ect ect...

Almost anything lighter than a nalgene will break if you don't leave a pocket of air in the neck of the bottle. Liquid doesn't compress the way air/gas does. If the air pocket is too small or non existent the nearly 200ft points of force generated by a 1l bottle dropped from three feet will easily overwhelm the structural integrity of a smart water bottle. Leaving an inch of air in the neck reduces stress on the smart water vessel to the extent that its very unlikely to be damaged by dropping from even much greater heights.

Another mistake is heating your plastic bottles in a dishwasher, this can also weaken or deform your bottles.

Nalgene 1 liter is the bottle I carry everywhere. Super light, never leaks, easy to wash, almost indestructible.

Some smaller Nalgene should fit in a car cup holder if that's important for you.

The Thermoflask Double Stainless Steel Insulated Water Bottle is the ideal water bottle for everyday use. Whether you’re going to the gym or running errands, this vacuum-insulated, stainless steel bottle has a comfortable grip with a convenient handle for carrying, and it fits in a standard-sized vehicle cup holder.

Basic Nalgene 32 Oz. Light, easy to carry, lasts forever, never leaks. I have a newer one that even seems not to sweat as much when there’s ice in it.

I like my vapur bottle because it’s lightweight and packable when empty. I strap it to my bag but I imagine it could fit into a bottle pocket.

16oz Nalgene. I like the smaller size because my adventures usually have frequent access to water or are shorter hikes. It’s also sized right if I feel the need to add a liquid IV or similar in there. Light and it’s inexpensive enough that I won’t cry if I lose it.

Camelbaks have always been unwieldy for me and everybody I know seems to have a leak in them.....difficult to filter into and too bulky.......yes, hydroflasks are very heavy (and expensive).......I just carry some leftover one-liter plastic water bottles (like Aquafina and those) I bought years ago....very light, never leak, just pop your filter hose into the top......yeah, it's not fancy or trendy, but I don't need to impress anybody.....

I always have a 2-3L Camelback and a Nalgene. The camelback for hiking, and for times you’ll want more than a liter with you. The Nalgene for where you may want to add electrolytes, Gatorade or other drink mixes.

Nalgene is light, durable and isn’t as prone to leaking as many with fancier lids in my experience. Also like $15.

One great advice I have heard over the years - stop counting grams of your gear weight, start counting pounds in the gym. :)

When I’m doing rim to rim in summer, I personally carry two 1.5 liter Thermos, so water and Gatorade stay cool by midday, spring or autumn - just plastic bottles in the backpack. So no weight overhead for liquids.

Always carry the water filter, regardless of the season and how much water you have on you.

Camelback. You want to be drinking every few minutes. A bottle just gets in the way. Must easier hands free.

Camelbak or something similar with a drinking tube. Makes it easy to drink while you are hiking, and so you will. And don’t drink just water—strongly suggest Tailwind or something similar with calories.
