The further you venture away from the trail head, the more important your gear becomes. Priority goes to the basics of survival – food,water and shelter. Modern clothing and tents make life much easier being lightweight and breathable and are now common place. Freeze-dried food now makes it possible to carry weeks worth of food on your back. Water however, is an essential requirement and we aren’t able to carry a weeks worth of water.
The ability to travel long distances well hydrated is greatly increased by the inclusion of two light weight items: A water microfiltration device and trekking poles.weblink
Trekking poles increase your stability on uneven terrain and allow the upper body to assist then knees in controlling the body during descent. As just about every trip involves plenty of climbing and descending they quickly become an important tool. Their benefits are amplified when you are carrying half your body weight on your back and when fatigue starts to set in they help prevent falls and injuries.
Safe drinking water is compulsory if you are going to stay well on the trail. Water is the home to viruses, cysts and bacteria, all of which can cause serious illness. Carrying it is usually impractical so the answer lies in light weight water purifiers. Modern devices have pores as small as 0.2 microns that stop the passage of all types of pathogens. They have the ability to turn any source into safe drinking water and come in a hand pump configuration or with the filter integrated into a water bottle.
