At this price point, we’re comparing Nalgene, Hydro Flask, Kleen Kanteen, and Stanley for non-insulated stainless bottles. This Nalgene model rises over the rest with its weld quality, cap seal, and overall durability. Otherwise, these stainless bottles all work well for survival purposes, being able to boil water to purify it.

Here is how the bottle measures up:

• 38-ounce capacity
• Stainless steel
• 3.5″ D x 8″ H
• 13.4 ounces (empty)

With a great price and solid durability- it’s easy to see why the Nalgene Stainless 38oz Water Bottle is the best.

Grayl makes a wide assortment of filter water bottles with impressive filtering capabilities and speed. The Ultrapress is one of the lower-priced ones, you can also find a titanium option for the ultimate survival water bottle (both included filter and the ability to boil the container). That one will set you back a few hundred bucks though, so it doesn’t make our list due to cost practicality.

Here is how the bottle measures up:

• 16.9-ounce capacity
• Polypropylene
• Electroabsorption, activated carbon filter
• 3.0″ D x 10.0″ H
• 12.5 ounces (empty)

If you are looking for an integrated filter solution, the Grayl Ultrapress Filter Water Bottle is what you need.

The Survival Water Bottles We Compared

Our research narrowed the field down to several types and brands of water bottles that we compared: Nalgene, Kleen Kanteen, Hydroflask, Grayl, Lifestraw, Sawyer, Rothco, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We considered a wide range of water bottles and narrowed it down to the integrated filter and metal varieties quickly. Traditional polypropylene (sports bottles) have their place but just didn’t offer the versatility we were looking for in a survival solution.

We’re always looking for new and better gear, so if you have a water bottle that you swear by, let us know in the comments. We review most of our tested gear annually so we can try to get it in the next roundup round and see if it will beat out our top picks.

While water bottles with survival filters are specifically designed for water purification, stainless steel water bottles serve as versatile containers for everyday hydration and various activities.

Water bottles with survival filters incorporate filtration systems to remove impurities and contaminants, making them ideal for outdoor enthusiasts and emergency preparedness. In contrast, stainless steel water bottles lack built-in filtration and rely on external water treatment methods if purification is needed.

Additionally, water bottles with survival filters require specific maintenance to keep the filtration system functioning effectively, whereas stainless steel bottles are relatively easy to clean.

Ultimately, the choice between the two depends on individual needs, with water bottles with survival filters being favored for water purification in outdoor or emergency situations, while stainless steel bottles offer durability and versatility for everyday use.

What to Look For

The best survival water bottle has several important features to look for:

1. Value
2. Functionality
3. Size & Weight
4. Versatility
5. Durability

When you get the right blend of these, you can find a bottle that you can rely on for a wide range of situations- ranging from long hikes to SHTF and everything in between. Below, we break down what each of these features means for the survival-oriented water bottles that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something like a water bottle shouldn’t blow out your entire budget. If you are getting one for a survival kit rather than everyday use, it may not make sense to spend much on a container.

You never want to spend too much money on one thing when it comes to gear. It’s better to diversify your survival gear to make sure you are covered for a wide range of scenarios.

Functionality

How well does a water bottle hold water? How much water can it hold?

These are a water bottle’s main functions, and if it can’t hold water well without leaking- or if it can’t hold much water at all then it’s not what you’re looking for.

At the very least, a decent survival water bottle has to hold a good amount of water.

Size & Weight

The size of the bottle typically scales with the capacity. You can easily find water bottles that will hold all the way up to a gallon, but that is a lot of size and weight to be carrying for most people in bottle form.

Steel bottles weigh more than plastic, but titanium is lightweight as well. Regardless, the water that you put inside the bottle will be much heavier than the bottle itself.

How much water you’ll need in a survival situation varies on your situation, but our handy water calculator can make it easy to figure out:

Versatility

Versatility is really where you’ll see different water bottles excel. The two main survival water bottle types (metal or integrated filter) bring versatility in how they purify water.

Durability

Metal water bottles are extremely durable, but you can still dent them and even break them if you aren’t careful. Many people opt to keep their survival water bottles in carriers to provide extra padding and convenience. This, or fitting a camp cup to the bottom of the bottle can enhance the durability.

Who Needs a Survival Water Bottle?

Everyone can use water bottles since they are useful for staying hydrated. But for survival, they go way beyond that. They are a tool for carrying and purifying water and a container for anything- even non-liquids.

For this reason, we consider them an auto-include in a variety of kits.

You’ll find a survival water bottle as an essential item in all of these kits:

Water bottles have uses well beyond survival
