What are the equipment and precautions for outdoor travel?
Basically need: breathe freely and comfortable sports clothes, mountaineering shoes, commonly used drugs, summer need some sunscreen, hats sunglasses such as sunscreen, food (look at the situation, maybe need some convenient, not heavy but top hungry food diet), drinking (or sports drinks, mineral water), toilet paper. If it's in the field, you'll need tents, sabers, compasses, binoculars, etc.
