How To Choose The Right Hydration Backpack?

Buying the right hydration backpack for yourself is quite simple if you look for the following essential features.

  • Water capacity: The first thing you need to look for in your hydration backpack is its fluid-holding capacity. If you need the backpack for a short trip, a small pack should be okay for you. But when you are out on a longer trip, you may want to carry a larger pack to last you through the entire day.
  • Drinking accessories: To be able to drink water from the bladder, you need to have a long, flexible hose. The hose functions well if it is properly connected to the valve. The valve has to be leak-proof, while the mouth of the hose should have a shut and lock feature to avoid leakage.
  • Extra baggage: After the water capacity is determined, check for how much of your items it can carry. You can opt for a backpack with multiple compartments so you are able to carry and organize your belongings easily.
  • Perfect fit: Just because you need more water, it doesn’t mean you can go for a large backpack. The backpack has to fit you perfectly, and all the straps should be easily adjustable.
  • Material: Hydration backpacks do not come cheap, so, look for an option made of good material to last you long. The fabric for these backpacks differs from brand to brand. The fabric should be breathable and not make you feel hot when it is on your back. Rip stop fabrics are considered the ideal choice, as they are highly durable and comfortable.
  • Straps: The backpack must preferably have sternum straps, padded shoulder straps, and a waist belt to distribute weight through your torso.

Frequently Asked Questions

1. How do hydration packs work?

Hydration packs are water sleeves that store water in the bladder. The water is filled through a wide, sealable opening. You can drink this water through a hose that is connected to the valve, mostly located at the bottom of the pack. The other end of the hose has a mouthpiece that comes with a locking system, so the water does not leak out.

The hose usually sticks out through holes on the backpack and hangs over your shoulders so you can drink water easily. The backpack compartment in which the bladder is stored is mostly insulated to keep your water cold for several hours.

2. What is the capacity of a hydration pack?

Regular hydration bladders in a backpack come in sizes that hold 1L to 3L of water.

3. What kind of liquids can the bladder hold?

A hydration pack is like a bottle that can carry any liquid. However, it is best to stick to only drinking water as it is easy to clean, unlike a sports drink or juices, which if stored in the reservoir for long can cause the growth of mold in the reservoir or even the tube. Aerated drinks or stronger beverages can also impact the quality of the pack.

4. Can I buy spare parts for the hydration pack?

Yes, the valve, hose, mouthpiece, and the other parts of most hydration packs are replaceable and easily found in the market.

5. Does the reservoir freeze in cold water?

In extremely cold temperatures, the water in the hydration pack can freeze. And to avoid it, you can ensure that the hose is insulated. Try to keep the pack close to your body as it can help keep the water from freezing. You could also fill the pack with warm water as the insulation in the backpack will retain its temperature for long.

Hydrations packs eliminate the need to carry a water bottle, which means less use of plastic. For a nature enthusiast, this is a great option. A hydration pack is easily accessible and allows you to sip or drink water even as you continue to cycle or trek. The list above consists of some of the most popular hydration pack backpacks. We hope it helps you find the best backpack hydration pack.
