If you are in the market for the best hydration pack, you may be wondering which one to settle for. It is even possible you will be tempted to buy the first one you see. We have prepared this guide to help you drop some dollars for the right pack. Let’s start with the various factors to consider when buying. 

Factors to consider when buying a hydration pack

Sharkmouth Tactical Molle Hydration Pack


There are two types of hydration backpacks: hydration waist packs and hydration backpacks. Hydration backpacks come in large capacity, over one liter, and are ideal for long hikes and cycling as they displace the weight on your shoulders.

On the other hand, the hydration waist packs can hold up to one liter and are suitable for short jogs. These ones are not suitable for running or cycling as they may bounce up and down. 

Reservoir capacity

Hydration packs come in varying sizes with a majority of them holding from a few ounces to three liters. Make sure to pick the right one for you.

Gear capacity 

Does the pack have extra storage compartments? Some hydration packs have extra storage compartments, and others only have the capacity to hold the water reservoir. Depending on your needs, make sure to choose a suitable pack.

Hydration pack fit

You don’t want something that will feel tight, or that will put on too much tension on your shoulders. Such a pack will make you feel weighed down and will restrict proper blood flow. For the best experience, consider packs that have included proper padding to ease the amount of tension put on your shoulders.

Bite valve shutoff switch

Has the pack included the bite valves? Bite valves prevent water from leaking out the end of the straw when it is dangling. This valves further make sure nothing leaks even if the valve is switched “on”.

Tube portal

The tube portal is the area where you attach the straw to the hydration bladder. Most bladders have one type of positioning. Luckily, newer bladders are beginning to have multiple tube portals making it easier to position the straws on either the right or left-hand sides.

Mouth opening

Bladders with wide-mouthed opening are easier to refill and clean. You can easily fit a sponge or brush in them unlike those with a small opening. We enjoin you to settle for one with a wide-mouth opening because it is easier to clean and refill.
