There are a whole bunch of things that you need for camping, but you absolutely, definitely need something to wear on your legs. Hiking pants for women and men are a good option. They cover you up nicely, and the best of them will keep you dry in the winter and well ventilated in the summer.
In particular, when buying hiking pants you want to give serious thought to getting a pair of convertible hiking pants. If you’re able to remove the bottom half of your pants and turn them in to a pair of shorts, you get a piece of gear that is far more versatile than just a pair of pants.
Even in the course of a single day you might have very cold temperatures in the morning, which are then followed by very hot afternoons, where you would want a pair of shorts. And then cold evenings, where pants would be welcome.
Every athlete knows the importance of hydration. Whether you are training or in competition, if you do not get enough liquids, it can cause dehydration. In severe cases, it will cause death.
