try and be creative. like people have said do something that makes you different then other skiers
Get to know the right people, and be very outgoing. Sponsors dont want to sponsor you because you can throw a seven, they want to sponsor you because you know mad people and they all pay attention to what you do, therefore, if you do something cool while repping a company, other kids will start supporting that company. Thats what sponsors get out of it. They are out to make money, and you, my friend, are volunteering to be their little bitch in exchange for some free gear and maybe free skiing.
