Hydration packs designed for various activities

Hydration packs have come a long way since they were first introduced by Camelbak. The hydarion pack or hydration system as it is sometimes called essentially built as a backpack or waistpack containing a reservoir or "bladder" commonly made of rubber or flexible plastic. The reservoir contains a capped mouth for filling with liquid and a hose that allows the wearer to drink hands-free. Most hoses end with a "bite valve" that opens when the user bites down on it; the valve may be protected by a dust cover. Some hydration packs are insulated to keep water from freezing or becoming warm. Reservoir sizes commonly range from 1.5 to 3.0 litres.

Hydration packs are commonly used for outdoor recreational activities, such as hiking, bicycling, and kayaking, as well as for military maneuvers. With such a variety of uses and hydration packs, it is therefore important to know how to choose a hydration pack.

Choosing hydration packs based on activity for use 

Most people choose a hydration pack based on the actiivty for which it will be used. Below are a few broad guidelines to help you choose.

  • Day hikers, backpackers , climbers - Reservoir only (2 or 3 liters), or hiker-specific hydration pack

  • Trail-runners, racers, fitness walkers - Waistpack or minimalist (1L) hydration pack

  • Road cyclists focused on speed - Small pack or no pack; traditionalists may prefer bottles

  • Recreational cyclists - Sleek pack with 1L to 2L reservoir and modest cargo space

  • Touring cyclists - Small to medium pack, but with larger (2L or 3L) reservoir

  • Mountain bikers - Large pack with ample cargo capacity; 2L to 3L reservoir

  • Snowboarders, skiers - Small to medium pack, 2L reservoir; insulated sip tubes

Decide on a resevoir size 

Hydration requirements differ quite a bit depending on the person, the activity, and the weather. A runner can easily sweat a liter (34 fluid ounces) an hour. Know your own body's needs and take into account how long you will be out for, and if you can refill along the way. The most common reservoir sizes are 50, 70, and 100 fluid ounces.

Warning: Its generally recommended that you drink 1 liter of water for every hour of activity. Yet any number of factors (temperature, elevation, personal health, activity intensity) could impact a person's hydration needs. However it is better to drink fluids regularly and generously, even before your thirst-alert mechanism kicks in. Using a hydration system gives you an advantage. Because fluids are so easy to access, you'll drink more often and as a result perform better.

Determine cargo requirements 

What do you need to carry besides the water? A trail runner might just want to stash an energy bar, while someone on a long day hike might pack a veritable picnic. Think about what you usually bring with you. The cargo capacities of hydration packs are measured in cubic inches.

The largest backpacking/hiking packs offer close to 2,500 cubic inches (41L) of cargo room and offer enough comfort and load-support features to perform well on light-and-fast overnight adventures. Other hiking/climbing packs are in the 1,800 cu. in. (29L) range and are well-suited for all-day activities.

Mountain bike hydration packs are a little smaller, with cargo space ranging from 1,400 cu. in. (or 23L, enough for all-day rides) to 100 cu. in. (3L, just enough room to carry a spare tube, CO2 cartridge, wallet and an energy bar).

It's essentially the same story for snowboarders and skiers. Some people want extra cargo room as a stash spot for extra clothing layers. Others want the smallest pack possible so they can wear it under a jacket and use body warmth to keep liquids unfrozen.

Road bike hydration packs and trail-runner waistpacks tend to be the smallest of the group. The reason: Hydration packs, originally created for cyclists, are meant to carry lightly on a person's back and generate minimal wind resistance.

Consider pack weight 

When choosing water and cargo capacity, also take into account how much the pack will weigh when full. 100 fluid ounces of water weighs about 6.5 pounds. That is a lot for a runner to carry on their back.

Choose insulated or non-insulated pack 

An insulated bladder sleeve and foam insulation around the hose will help prevent freeze-up in winter. Conversely, the insulated sleeve also keeps cold water from heating up too rapidly in hot weather. These can be nice features, though they do add to the cost of the pack.
Cold weather: 1) Fill the reservoir with warm water to resist freezing. 2) Routinely perform a "blow back" in your sip tube when you've finished a water break. If you push water out of the tube and back into the reservoir, water can't linger in the tube and freeze.

Hot weather: It is ok to freeze a reservoir and its contents. Just be sure to leave room (perhaps one-quarter of the reservoir's capacity) for the liquid to expand as it solidifies. Do not fill the reservoir to the brim and then attempt to freeze it. If you do and then seal the reservoir, it could potentially burst. You can also use an insulated reservoir and tube to preserve the temperature of cold water on hot days.

Do you need a Sternum strap? 

Always a good idea, a sternum strap keeps the shoulder straps in place, no matter the activity.

Waist belt 

Envision a pack when it's fully loaded and how it will ride on your back. If you anticipate carrying large loads, look for a waistbelt. In fact any hydration pack that weighs six or more pounds when full should include a waist belt. This will keep the pack from flopping around too much when you run and jump.
