Buyer’s Guide

At times it may seem there is little that separates hydration packs from one another, but when we look closely we notice features, design elements, and potential red flags that make one pack a much better purchase than another.

In any outdoor activity, the struggle is to match fluid intake to fluid loss. In the interest of helping you find the right hydration pack to help you do just that, this buyer’s guide will focus on three main characteristics: bladder size, storage capacity, and ventilation.

Bladder Size

The packs we mentioned about offer bladder sizes ranging from 1.5-liters to 3-liters. To put water consumption in perspective, the average human body needs about five liters of water per day in a moderate climate with little activity (2).

Keep in mind, that figure is for a full, 24-hour period. All of these hydration packs are designed for daily use, so the real question comes down to how much water you think you’ll need for your most typical recreation activity.

In general, runners tend to carry less water because carrying extra weight takes a toll on knees and ankles. Cyclists also like to be as lightweight as possible, but mountain bikers and day hikers tend to carry a little more because they may be out for longer periods of time.

Storage Capacity

You’ll begin to notice a theme here, but how much additional storage you want in a hydration pack depends on how you’re planning to use it. If you’re a day hiker who won’t go out without the 10 essentials (3), for example, you’ll need to know how much space you need for gear in addition to water capacity.

Most hydration packs for runners and cyclists feature enough storage capacity for a phone, minimalist bike tool, and not much else. Because you’ll mostly be using these packs for shorter durations and (for cyclists) you’ll probably still be within the range of timely assistance if you do have a flat or breakdown, this lack of storage capacity isn’t an issue.

For mountain bikers and day hikers, especially, this extra storage capacity is vital. Deciding just how much you need, however, requires careful calculation of the combined volume of your raincoat, snacks, first aid supplies, multi-tools, and other essential gear.


Over the years, ventilation has become an increasingly popular feature of the industry’s leading hydration packs. Because endurance athletes pushing themselves to the extremes often use these packs, a little extra ventilation goes a long way.

Ventilation can be added in the back, shoulder, and waist areas of a hydration pack. Packs with more open mesh and fabrics in these areas tend to provide better breathability. Many are now integrating mesh-covered foam back pads with air channels for even better ventilation.

The average human body loses between 500 and 800 milliliters of water through perspiration every day with average activity levels (4). As you run, bike, cycle, or hike, your water loss through perspiration only increases, so selecting a pack with great ventilation is extra important.

Frequently Asked Questions

If you’ve owned a hydration pack before, you’re probably familiar with how to operate the hydration system, how to pack other items for a more comfortable fit, and how to properly wash and maintain the bladder, among other things.

With that said, there are inevitable questions that arise as you find yourself in different situations on the trail or road. For both experienced and new users of hydration packs, we’ve put together a useful list of frequently asked questions regarding this type of backpack.

Who invented hydration packs?

Camelbak is credited with the invention of the hydration pack back in 1989 (5). The company’s founder, Michael Eidson (an EMT by trade), was competing in a 100-mile road cycling race when he decided to fill an IV bag with water, slip it into a tube sock, and stuff the whole thing into the back of his bike jersey. Thus, hands-free hydration was born.

What is EVA material?

EVA stands for ‘ethylene vinyl acetate’ which, you guessed it, is a copolymer of ethylene and vinyl acetate. It’s an elastic material similar to rubber, but much tougher. It is mainly used for hydration bladders because of its waterproof and ultraviolet (UV) resistant properties.

What is TPU material?

TPU stands for ‘thermoplastic polyurethane’. It is a hybrid mixture of hard plastic and soft silicone. It is used in footwear, adhesives, and for specialty molding.

What is BPA?

BPA is the abbreviation for the chemical ‘bisphenol-A’. It is a chemical that is added to many commercial products, such as food containers and hygiene products. There are also chemicals known as BPS (bisphenol-S) and BPF (bisphenol-F) that may have the same effect on the body as BPA (6).

How do I properly wash my hydration bladder?

The common recommendation for cleaning a hydration bladder starts with a mixture of hot water and two tablespoons of baking soda or bleach. The solution can be mixed in the bladder. Then, hold the bladder above your head while pinching the bite valve and allowing the water solution to run through the tube. Let the bladder and cleaning solution sit for about 30 minutes before rinsing and drying thoroughly.

What do I do if my hydration tube gets clogged?

In colder environments, some hydration tubes get clogged when temperatures dip below freezing. Some packs offer insulated tubes, but if your tube does get clogged alcohol works pretty well as antifreeze.

Is there a pack just for kids?

Yes, Camelbak makes a great hydration pack just for kids, it is called the Camelbak Kids Mini M.U.L.E.

Can I put hot water in my hydration bladder?

While it’s generally not recommended to do so, many bladders can handle water upwards of 100 degrees Fahrenheit. NEVER, however, put boiling water in your bladder as it may damage it irreparably.

What happens if I lose my bite valve?

Bite valves are possibly the most easily lost or damaged piece of any hydration pack. Fortunately, most manufacturers (as well as Amazon) sell replacements.


There’s possibly no worse feeling when you’re outdoors than discovering you’ve run out of water. The right hydration pack ensures you have plenty of water for any activity and allows you to refuel on-the-go without fumbling to pull a large water bottle out of your pack. So, it’s time to find the right hydration pack before that summer heat really settles in. We hope you’ve found this article helpful and we wish you the best of luck in finding the perfect hydration pack for you!
