Just go try shit on and see what you like. Like they said before, who cares what everyone else thinks.
Or, you could buy the most expensive coat that you can find. I'm sure there won't be too many of those out there on your mountain... at least not till next season
I usually try to find something that's sort of lower profile and high techy. I like pockets, gaiters, and all that other good shit.
Just don't buy Burton... Unless you buy their top line the shit sux and has no features. O and is way more expensive than it should be.
