Replying to School Ski Trip Hoodies

One of the teachers organising our school ski trip down to Perisher in September has asked me to make a logo for the hoodies. Any ideas on what I can do. I'm shit ass at graphic design but can get by. I just don't want to make something super fucking wack for the school trip. The teacher is pretty chill and finished a gap year in Banff last year so I can pretty much do whatever the fuck I want for it. Any suggestions would be much appreciated.
