Snowboard hair?

Question

HI! When I go snowboarding I tie my hair in a ponytail and wear a hat. I'm not really that bothered by hat hair but the thing is after an hour of going down the slopes my pony tail has come undone and my hair is all matted w/ snow and its a pain to always have to retie my pony tail. Any suggestions of what I can do besides chop all my hair off? Thanks!
