Hikers and backpackers of old have long carried their drinking water in a canteen, water sling or, more recently, sports bottle. The popularity of outdoor sports, combined with a better understanding of dehydration, has led to the development of a more advanced, high-tech drinking system – the hydration pack. It is a type of hydration system built as a backpack or waist pack containing a reservoir or a bladder. Campers, hikers, riders and mountaineers have been using Hydration backpacks for decades. It allows them to have their hands free when climbing over a wall or even during their ride.
