Water is a vital element for any human being. Whether you are going on a trek or you are a survivalism enthusiast, it is essential to be able to keep drinking water for an adequate hydration. It is indeed possible, with your energy and fire equipment to boil water in order to purify it. However, there are materials and products specially designed for faster water treatment and purification.
The most practical are without doubt the filtering gourds and water bottles. Jerricans, water rations and survival bottles are available in different volumes and allow you to stay hydrated while having a sustainable supply of drinking water. The filter straws are also a great help in getting drinking water quickly. Water, by the way, is not limited to meeting hydration needs. Potable water is also essential for hygiene, which is why it's a good idea to include a collapsible bucket or collapsible food-grade plastic jerry can in your pack.
