1. Insulated Water Containers (Avoid)

Stainless steel insulated water containers are great for keeping water nice and cold at the office or on a picnic, but are not so great for backpacking. You should avoid taking a hydro flask on your hike. As a result of the heavy weight, insulated water containers are ranked as the worst type of water bottle for long-distance backpacking.

2. Nalgene (Avoid)

Plastic, reusable water containers, such as Nalgene bottles are super popular for day hikes or everyday use. However, they are really heavy when compared to other alternatives on trail and should be avoided for long-distance backpacking or thru-hiking.

3. Recyclable Plastic Bottles (Consider)

Recyclable containers are great for long-distance backpacking and thru-hiking because they are lightweight, affordable, and easy to obtain in trail towns. Smartwater and Dasani 1-liter bottle threads match up with the popular Sawyer Squeeze water filter. This makes the Smartwater and Dasani bottles very popular on long-distance trails since a lot of thru-hikers filter their water with a Sawyer Squeeze.

Smartwater Weight: 34 grams (1.4 ounces)

4. Soft Shell Water Containers (Consider)

Soft Shell water containers (or water bags) are great for long-distance backpacking and thru-hiking because they are super lightweight and pack up small when not being used. The Platypus and Evernew brand water bottles are lightweight and are designed to be reused.

Platypus 1 liter Weight: 34 grams (1.2 ounces)

Platypus 2 liter Weight: 37 grams (1.3 ounces)

Evernew 0.9 liter Weight: 28 grams (1.0 ounces)

Evernew 2.0 liter Weight: 43 grams (1.5 ounces)

Retail: $9 and $15 respectively


The soft shell water containers like the Platypus and Evernew brand bottles are lightweight and designed to be safely reused. However, the Smartwater and Dasani type bottles come very close in weight, have threads that match the Sawyer Squeeze water filter, are very affordable, and are easy to replace in trail towns. This makes the Smartwater or Dasani water bottle a very close competitor.

If you need to carry a lot of water, I recommend the 2-liter soft shell water bottles like the Platypus or Evernew bottles because of how light they are and their large water capacity. However, you should quickly transfer your water to smaller water containers when you get a chance. You don’t want the 2-liter container leaking in your pack.

I do not recommend carrying more than 2-liters in one water container because a small leak could be catastrophic.
