Replying to Tall Teee Length???

Ok so i got out my colletcion on tall tees today and lined them up and checked out there sizes. I put them all one and checked at were they all whwent downt to. One whent down to my knees (light blue) , one whent to like 4 inches above my knee (dark blue) , and one whent like 2 inches past my knee (red). Now i know that they all are different in a way and they all mean like a different kind of thug or gangsterness. So, im going on a camping trip in two days and i was wondering what the best tall tee would be for me to go camping in. And also which one would be good for skiing and which one would be good for causual things like getting gas and food at a gas satation? Im just confused and whant to know what you guys think and what your opinion on this is???? I hope this makes sense im a lilttle out of it now. thanks
