Why use a hydration pack instead of a water bottle?

  • Easy to drink on the move:  One of the most tedious things for any athlete who is in constant movement during their training, as a cyclist or runner, is having to stop or slow down to drink water from a bottle. However, hydration packs are the perfect multifunctional solution for this malady.
  • Easy to stay hydrated: We can add that these hydration bags, due to their especially comfortable design, motivate you to drink much more water than you would drink with other hydration methods, whether you are on the beach or practising water sports. In addition, most of them can contain between 2 and 3 litres of water, which is especially beneficial for hikers who can do more on the road by making fewer stops to stock the backpack with more water.

Types of hydration backpacks


Most of the hydration backpacks do not give all the space to the storage of the water, because they allow ensuring the hydration for no more than a day of the excursion. This is why they usually leave a very good space for clothes and personal items, but sometimes they do not have a great capacity for water storage.

That is not something beneficial for those who carry out such a demanding activity and in which they often have help from miles away. So, no matter what the size of your backpack, we recommend that you really look at the capacity of water you have. Sacrifice space for anything but water.

Road cycling

If you are a road cyclist, your first choice has to be bicycle backpacks. It is proven that it is more beneficial for the balance of the bicycle to carry the weight on it than on the cyclist’s back.


The most important thing for those who practice this activity is that the backpack does not bounce. That is why it is important to have a lightweight and mooring system that allows stability. For this, in the market there are two styles specially designed for running comfort:

  • Vests to run:  They have the design of a vest and have a lanyard that allows fitting very well to the body. Although they look like regular backpacks, they are less visible and have front pockets and tie-down straps like shoulder bags, but do not have a lumbar belt. Most vests also have hydration tanks, although they are sometimes sold separately and others include dedicated water storage facilities in their design.
  • Backpacks to run:  They have the design of any common backpack of simple excursions, of a day. However, they have operating characteristics specifically designed for this activity, such as a discreet design, some have a lumbar belt, pockets easily accessible for the runner who has more storage than the backpacks to run, most have a good hydration capacity to drink water while running.

Snow sports

Hydration backpacks are excellent for outdoor sports such as skiing and snowmobiling because they can be used perfectly without having to go through the tedious ritual of removing gloves. Although some users find a greater benefit of buying a hydration backpack.


It is best to look for light hydration backpacks with a thin layer or shell that protects it. In addition, it must be taken into account that the hydration reservoir should be adequate for about 5 or 15 hours of activity in these mountaineering activities. And, in most cases, an extra hydration reservoir is placed.


Most backpackers do not usually have higher expectations or demands on their hydration backpacks. Due to the nature of their activity, they tend to prefer more storage for their clothes on the trip and other belongings, since they do not usually have problems filling the water tank of their backpack constantly and do not usually require so much hydration, at least not constantly like others of higher demand such as hiking or cycling.

Waist bag

You may have noticed by its name, these are a variation of the hydration backpacks that are placed around the waist. Most include water bottles instead of a deposit. By their nature, they are designed to store very few things, only the essential ones. This is why they are ideal for short-term activities such as running, skiing or short walks, for example.

What to look for in hydration backpacks?

Comfort and stability

One of the reasons to buy a hydration backpack is that they are lighter and thinner than a normal backpack. In fact, even the largest ones are quite narrow, thin and convenient. The smaller ones direct the weight to your back or in the lower part of the waist. 
Look for models that stay in place as you are running.

Tube compatibility

Many of the most popular brands use hoses compatible with each other, which is quite practical to try several options from different manufacturers until you find the one that makes you more comfortable without dripping.

Pressurised or non-pressurised

With pressurized systems you do not have to suck, since a second hose applies pressure so you do not have to make almost effort to take. 
They are quite comfortable, but they are not really necessary and they do add some weight to the system in general.

Ease of cleaning

All backpacks must be cleaned regularly. As they are reusable, you have to avoid creating dirt and growing bacteria or fungi. In turn, if you are taking sweetened drinks or powdered electrolytes, you have to clean the entire backpack every one or two uses.

  • Clean the reservoirs: the bags that open at the top are the best and some can even be washed in the dishwasher. If the opening is wide, it is also easier to wash it at depth and dries faster too. Sometimes you can also use brushes to clean better.
  • Clean the hose: especially if you drink with sugar, you have to clean the tube thoroughly with a brush and soapy water. In fact, there are kits to clean them that include these convenient


In this section we talk about the capacity of the water bag and the hydration backpack in general, to carry your equipment and accessories:

  • Reservoir capacity:  Remember that each liter of water weighs 1 kg, so you must take into account the amount of water you want and need to drink normally and buy a backpack suitable for that need. Sometimes it is advisable to have the highest capacity model, but fill it just where you need it. There are 1L, for mild activities, 2L for longer and stronger training and 3L for high performance, people who drink a lot of water or hot summer days.
  • Equipment capacity  The capacity of the backpacks to carry your equipment and accessories can go from 5 to 50 liters. Before choosing a specific model, think about everything you need to carry and the size of the bag. If you only go hiking, hiking or short races, the little ones are enough. the medium ones are better for running, camping and climbing mountains, while the bigger ones are better for mountaineering, long climbs and should be waterproof and breathable.


You need a bag that fits you well so that everything maintains a correct balance, your back does not suffer and so you can go with total comfort. To achieve this adjustment to your body, look for a model taking into account the following:

  • Length of the torso: the backpacks come in different sizes that fit almost any torso, from short to longer. In fact, some products come with adjustable suspension to fix your shape.
  • Waist size: these products can adjust many waist widths, in measures of 63.5 to 101.6 cm or more.
  • For women: these shoulder bags have ergonomic shapes designed specifically for the woman’s body, so the torso is narrower and smaller.
  • For young people: they have lower capacity and come with adjustable suspension to graduate to the child’s body as it grows.


  • Closure of the bite valve: some valves can be turned to close them securely, while others have a switch to avoid unnecessary spills.
  • Portal for the tube: they are holes in the backpack that allow to pass the hose through it. Some models bring two holes or one in the center of the backpack.
  • Clips: these are placed on some of the shoulder straps and serve to keep the hose in place and make it easy to access and use it.
  • Quick disconnect tubes: some reservoirs have easy disconnect systems to quickly remove hoses and fill in a few seconds. You only use a button to disconnect both parts, take out the water bag and leave the tube in its place if you use it through a portal.
  • Wide opening: if the bag has this, it will be easier to pass the hand inside to clean it. You can even use a brush and get to the bottom. On the contrary, if it is a small opening, you can buy a special cleaning kit for these products.
  • Accessories for cold climate: there are accessories for the temperate climate, such as hoses and bags with insulated insulation or covers for the nozzle. They can be useful, but they also add some weight.
  • Protection against rain: these waterproof covers are great if you do outdoor sports.
