When you are planning to go trekking or hiking, you have to make sure that you are equipped with the right supplies and clothing. If you are just doing a simple day or half-day trip on easy terrain you’ll probably don’t need any special gear. Just make sure not to wear classy leather shoes and other noble clothes, because when you leave the asphaltic streets they will become dirty by any means. So put on some old stuff and you’re ready. If you are heading to more complicated and remote terrains or to longer treks you will need more advanced gear to “survive”. The first important thing are the right boots. If you don’t have the right footwear you will end up with blisters and pain very fast. You should at least wear hiking boots with a half high shaft. But when you are on longer trekking tours and on higher mountains you need sturdy trekking boots with a high cut to protect your knuckles and to prevent yourself from spraining your foot. You really shouldn’t be stingy when looking for the right boots because surefootedness is very important in the high mountains. Another thing to look for is, if they are waterproof because you don’t want your feet to get wet. You should make sure that the boots use a Gore-Tex or a similar membrane. These are watertight and in the same run breathable, what is also very nice because your feet will not sweat that much. If you are moving on icy terrain you should consider to buy spurs for more grip. And if you have bought the right boots you have to make sure to tie them right because your feet shouldn’t slide around in your boots. Another important thing is to have is the right backpack. It’s the same again here. With longer tours and harder terrain the required professionalism rises. On longer trails you will need much more space to pack your stuff in, such as clothes, provisions, a sleeping bag, a tent, a stove and many things more. So when you are buying your backpack you should consider if it is big enough, and if you can bear it. To make rucksacks easier to carry, the bigger ones come with an hip belt. So you don’t have to bear all the weight with your shoulders, it gets divided between them and your hips. The backpack seems to be much lighter like this. When moving in the higher mountains and on snow telescopic sticks can be nice to give yourself more stability. When going uphill or downhill they can support the legs and especially the knee joints. Also your jacket shouldn’t be a cheap one when going on a longer tour. It’s very important to have a good jacket which is impermeable to water and also breathable to give you the best comfort. Again the Gore-Tex membrane is a good choice here. When hiking on higher mountains it is essential to have a good jacket to keep you warm. To make your winter outfit complete you should get gloves and a warm headpiece. I hope that i could help you a step further with your considerations about outdoor clothing.
