Well you should wear full metal armour and weigh your bag down with rocks. That will help. Not! Most hikes I would wear shorts, but you should make sure that there are no snakes. If there are snakes you would be better off wearing jeans. You should carry a mobile and keep it in a glad bag, wear a hat and shirt. I've been on lots of hikes. At the moment it is Summer but if you live in a cold place disregard everything I've said
