Backpacks with drinking system outlet

Withdrawal of the drinking system

— this feature allows you to use sports drinking systems with a backpack: a soft water tank is installed in a special compartment, and a tube with a valve is brought out through a separate hole and attached to the strap. Thus, the athlete can drink without removing the backpack and without even stopping. The drinking system itself (hydrator) is usually not included in the kit, but there are exceptions — they are placed in the appropriate selection point.
