You’ve just arrived at your camp site and you’re unpacking the Jeep. In it, you have a tent, a grill, all of your hiking and climbing gear, plus bear spray, of course. But wait— you left all of your bottled water at home! With so many fun outdoor activities plans, what are you going to do?

Ladies and gentlemen, meet the emergency flask, otherwise known as a camping flask or backpacking flask. You should always have an emergency flask if you, especially if you’re in the great outdoors. These flasks are the best that the market has to offer in terms of materials, dimensions, caps, and of course, prices. Let’s get started!

Editor’s Pick

Stanley Classic Flask

My favorite emergency flask is the Stanley Classic Flask, available in green, red, gray, black, and blue. It’s perfect for storing water, of which you should always have a backup source. 

Pros: At only 1.5 by three by 7.5 inches, the Stanley Classic Flask can easily fit into your pocket. It weighs only 5.6 ounces but holds eight fluid ounces, which is pretty efficient. I also love that it’s cap is connected to the bottle itself, because I am over losing my bottle caps.

Cons: Unfortunately, the cap is made out of plastic and seems a bit flimsy.

Top Contender

Top Shelf Flask and Funnel Set

Made of a strong stainless steel, this flask doesn’t disappoint, especially when you consider it’s price at about half the industry average. Whether you’re camping, backpacking, skiing, or hiking, this set will make sure that you’re always properly hydrated. 

Pros: For it’s flask and funnel set, Top Shelf offers it’s customers a lifetime guarantee! Shockingly, it’s one of the only flasks I’ve reviewed to come with a funnel, which makes pouring much easier. It’s also perfect if you’re looking for a small flask, as it measures only two by two by four inches. 

Cons: Now, I don’t know what you’re planning on using your emergency flask for, but if it’s alcohol, beware: leaving alcohol in the Top Shelf Flask for a few days will turn it black and metallic-tasting.

Best For Skiing

Gifts Infinity Stainless Flask Set of 6

When we go skiing, it’s typically in large groups— got to take advantage of those family packages! That’s why, if you have a ski trip planned, I recommend carrying a flask from Gifts Infinity, available in sets of six for an incredibly low price. 

Pros: Made of stainless steel, you can rest assured that these flasks are durable, even if they get buried in the snow. I also appreciate that the caps are attached to the flasks, as you’ll no doubt be gallivanting from the slopes to the ski lodge to your room dozens of times. This is perfect not only for skiers, but for any group of people embarking on an outdoor adventure where fresh water isn’t readily available. 

Cons: Despite the allegedly “stainless” steel, I found that my Gifts Infinity flasks got scratched up and dented pretty easily, although they never broke completely.

If you’re a hiker, you’re probably concerned about the environment in general. That’s why you’ll love the GSI Outdoors 18 Oz Flask, which is made from 100% recycled pet plastic along with BPA-free resin. 

Pros: Available in 18 or 10 fluid ounces, this flask from GSI Outdoors weighs less than the industry average at only four ounces.

Best For Backpacking

SportFlask Flask

At only .3 ounces, the SportFlask Flask is the lightest flask that I’ve ever reviewed. That’s why it’s used by fighter pilots, and why it’s perfect for backpackers as well. 

Pros: Backpackers like to keep things as affordable as possible, which is why I recommend to them the SportFlask Flask, which costs about half of the price of competitors. It holds 16 ounces, otherwise known as two cups, of fluid. Plus, it comes with black, silver, pink, brown, or green, giving you a lot of options to express your style. 

Cons: I found that the SportFlask Flask’s cap was a bit leaky, which was frustrating.

Emergency Flask Methodology

What exactly should you be looking for an emergency flask?

  • Material: The majority of emergency flasks are made out of stainless steel or plastic. Surprisingly, plastic flasks actually weigh more but tend to be less durable, so I prefer stainless steel. Of course, stainless steel flasks may make your drinks taste a bit metallic if you leave them in for too long, so that’s something to keep in mind.
  • Dimensions: Depending on how you’ll be storing it, you want a flask that holds the greatest amount of liquid in the smallest space possible. Most emergency flasks tend to be about one inch deep, a few inches wide and anywhere from four to nine inches high. For backpackers and hikers especially, I would recommend prioritizing small flasks that hold large amounts of water, like the SportFlask Flask.
  • Weight: The average flask that I’ve reviewed weighs a little over six ounces. Again, if this is something you are going to be carrying for an extended period of time, make sure it’s not too heavy.
  • Fluid ounces: Emergency flasks typically hold eight ounces, or a cup of liquid, although I’ve seen options go as high as 18 fluid ounces.
  • Cap: Most flasks have screw on caps, but I prefer the ones that are attached, as they’re super easy to lose.
  • Warranty: I prefer emergency flasks that come with a lifetime warranty, like the options I wrote about from Top Shelf and GSI Outdoors.
  • Price: The average flask that I’ve reviewed costs around $12.35. I’ve seen them go from about seven dollars all the way up to 18.

Emergency Flask Tips

So, what are some best practices when using your emergency flask? I thought you’d never ask…

  • No alcohol: If you’re doing an outdoor activity, it’s best to stick to water and avoid alcohol, which can make you dehydrated and less safe.
  • Camel up: Even though you have an emergency flask, it’s important to drink a lot of water before you leave your camp site each morning, along with every time you pass by a water source. This way, you’ll always be hydrated and can carry less water in your flask.
  • Filter: You can filter the water in your emergency flash by either using a mini filter or purification tablets.
