Filling
Drinking systems are usually filled with tap water so that the system can simply be dried after use. The use of sugary or isotonic drinks is possible in principle, but cleaning the drinking tube is then more complex. To avoid mold, the inside is then scrubbed with a thin and flexible brush. As a solution, several manufacturers offer sugar-free effervescent tablets that add salt and flavor to the water without significantly increasing the cleaning effort.
Temperature resistance
Most systems are based on polyamide (nylon) or polyurethane . Both fabrics are only heat-resistant up to around 50 ° C and must never be put in the microwave. Although the substances can withstand temperatures down to −20 ° C undamaged, there is a risk that frozen drinks will expand and tear the drinking bag from the inside. It is therefore recommended to fill the drinking bag only halfway below freezing point and to insulate it inside the backpack.
