Use resistant and pliable pants or shorts and preferably polyamide or other quick-drying fabric;
Do not use jeans, because that fabric retains the movements and the perspiration;
Avoid colors or camouflage patterns to facilitate where you are in case of emergencies;
Coat or other warm clothing for when you arrive to the end of the activity or to wear every time it is cold or raining;
A cap if there is a lot of sun, the head is our biggest temperature radiator;
Boots for trekking or, if you don´t have ones, a pair of quite sturdy and comfortable tennis, preferably with ankles protection;
Appropriate socks are essential, such as a spare pair to change if you get wet;
Sunscreen and sunglasses, even if it is cloudy.
