A hydration bladder is a portable container or bag used to store a liquid, such as water, to keep the user hydrated in an easily accessible manner. Hydration bags are often part of backpacks or a separate smaller bag. These drinking bags for airsoft games are very useful, where rehydration is important because it is possible to hydrate without removing the mask through the opening of the drinking bag.
The drinking bags contain an internal water tank (into which the liquid is poured) and a tube that allows you to drink the liquid without having to take off the backpack or take off the protective mask, because the tube easily fits underneath. On the pipe there is a sipes that allow a controlled flow of liquid.
Hydration bags are great for hydration and rehydration, especially in situations where water is not readily available. Those who participate in longer airsoft games often choose hydration bladders because they are convenient and efficient in terms of water consumption.
Drinking bags are available in different sizes, shapes and colors.
