What do you mean going camping? Is this supposed to be a military question.
If it was, you would know that if you were 'camping' or in the field, you would be lucky to get a shower once every 4 days and would know that you have to keep your hair up according to uniform standards while you are in uniform.
The only time you get to take it down in the field is when you are sleeping, and then it isn't even a good idea. Those middle of the night guard duty shifts isn't the time or the place to be jacking around with your hair.
